It is difficult to increase the resolution with a video microscope.
This is due to the limited resolution of the video signal itself.
Possible ways to improve resolution are:
1. How to use a Full HD signal
2. How to use analog RGB signals
We provide full high-definition microscopes that support high-definition signals. This microscope achieves high resolution while maintaining the smooth movement of a video microscope. It is a type that does not require a PC and can be connected directly to a monitor.
Since each signal method such as video, HDTV, and analog RGB, as well as the shape of the terminals, are different, care must be taken when using them.

This article presents the key points, usage, and recommended microscope models for using the measuring capabilities of microscopes in the context of quality control.
Although some microscopes are equipped with measurement capabilities,
However, their use can be difficult due to the following two problems
(1) Microscopes themselves may not be measuring instruments that guarantee traceability.
(2) Except for high-performance models, calibration must be performed by the end user.
(This may lead to errors due to user manipulation.)
When used for quality control purposes, there is no problem if in-house calibration is performed.
However, in such cases, the reference standard used should be clarified.
In short, use is feasible if the following three conditions are met.
・Select a microscope with high reproducibility.
・A reference standard that can confirm the accuracy of the selected microscope is clearly available.
・The company possesses a traceable reference standard.
ISO 9001 certified companies also use these standards.
For the use of length measurement functions in quality control, we recommend the
CT200HD series microscopes
Data from the lens is transferred to the camera, which automatically utilizes the built-in calibration data.
・No need for user adjustments
・No measurement value discrepancies caused by user operation
Calibration certificates and test reports can be provided for glass scales (for a fee).

Basically, it is more stable to connect directly to the USB port of the PC.
(If the power supply of the PC is vulnerable, the self-powered HUB may be stable.) ）
There are a few things to keep in mind when using HUB.
If you use the USB 2.0 type, it basically does not work.
However, if you adjust the number of clocks on the camera side, the image may be displayed.
However, the speed is extremely slow, and the low-resolution camera is reflected, but the high-resolution camera is
Abnormal operation such as not being displayed may occur.
Especially if you are using a notebook PC, using USB bus power will increase the supply current to the camera.
It may be insufficient and show abnormal behavior.
Of course, it depends on the capacity of the power supply on the PC side, so it may work without problems.
(supplement)
Even if you choose a USB 3.0, self-powered HUB, the communication speed of USB 3.0 may be limited.
There are some HUBs that are not listed.
(Depending on the HUB, communication speed may decrease.)
In this case, the low resolution (low amount of data) camera will work, but
High-resolution camera (large amount of data) Abnormal operation such as camera not moving occurs
There may be cases.
If the C-State function of the PC is enabled, some symptoms may occur.
C-State is a feature that switches the CPU to a low-power mode to reduce the power consumption of the PC. This feature can cause insufficient power supply via USB, resulting in video delays and unstable video display when using devices such as USB cameras.
In Windows 10, C-State is specifically enabled for the purpose of extending battery life and saving energy.
C-State is a separate feature from the energy saving mode in the power plan. If changing the power plan from Energy Saver or Balanced to High Performance does not help, it is recommended to disable C-State.
It is possible to disable C-State from the BIOS, but since the BIOS settings vary depending on the manufacturer, it is difficult to generalize the specific operation method.
For instructions on how to disable C-State, please contact our support.
We propose two simple devices that allow an object to be moved and its four corners easily observed with a microscope.
■Proposal 1
In this method, choose a material that is softer and slipperier than aluminum.
(e.g., polyacetal (a material suitable for gears used without lubrication, etc.))
■Proposal 2
We suggest the use of a slide table that can be moved in the XY direction.
A video signal is a general-purpose video signal.
One of the advantages of using a video signal is that you can take advantage of a variety of external devices at a low cost.
In this article, we will introduce some recorders.
This is the conversion cable introduced in “How to convert video signal to USB”. Since it is recorded using software on a PC, it is possible to record still images and videos depending on the software.
What is a bit unusual is that it is a battery-powered recorder. It is made overseas, but it can also be purchased on Amazon and other sites.
You can record not only videos but also still images.
This body is the recording medium. The recording data will be downloaded to your PC via USB. I can’t print it to the screen because there is no output.
The video signal recorders we sell can record both moving images and still images. The GRAV-1 is a split-function video camera that supports USB memory. The storage medium is a USB memory. You can record videos and still images. It is also possible to save with an external trigger. (Still images only. * There is also a special order memory for videos.

 |
For video signals, video recorders are the mainstream. If you don’t need to store still images, there are a number of low-cost options.
Small video-only DVRs are sold as security equipment.
There are many inexpensive hard disk recorders on the market.
The camcorder is also suitable for long-term recording.
Introducing a hard disk recorder with a screen that can record for up to 2 months.
There is also something called a skip-back recorder.
Records images before and after the shutter is released by a sensor or other device.
I think the easiest way is to use a USB-connected video capture device.
It comes in a variety of formats.

With a video microscope the photos you took using the converter to convert NTSC to USB displayed on your PC. |
We will also introduce you to the recommended converters. Don’t hesitate to contact technical support.
Our camcorders usually come with a BNC to RCA video cable in the box. BNC connectors have a locking function, while RCA connectors have a plug-in design.
In environments where the cable is frequently moved, RCA connectors are not suitable. For this reason, the majority of flex-resistant coaxial cables on the market are BNC type cables at both ends.
There are many products on the market, such as:
If you want to use one of the terminals with RCA, you can buy a cable with a bend-resistant BNC terminal and install the RCA terminal yourself if necessary.
Alternatively, you can attach the following conversion plug to a flex-resistant BNC-BNC cable.
There are no clear regulations for video cables as there are for USB cables.
For video signals, the optimum length is approximately 10 m when using ordinary pin cords (RCA terminals).
When using coaxial cables (BNC terminals), signal degradation is hardly noticeable even at lengths of 100 to 200 meters.
If you prefer to use RCA terminals, products are available on the market that use RCA terminals for terminals and coaxial cables for cables.
There are no clear regulations for video cables as there are for USB cables.
For video signals, the optimum length is approximately 10 m when using ordinary pin cords (RCA terminals).
When using coaxial cables (BNC terminals), signal degradation is hardly noticeable even at lengths of 100 to 200 meters.

There are various types of conversion connectors and cables for video signals on the market.
Below is the cable that comes with our 12-inch monitor.
If you want to connect this to a device with BNC output, an RCA-BNC conversion connector is convenient.
(If you attach an RCA-BNC conversion connector, you can connect to a BCN type camera.)

Video signal is a widely used video transmission method, and many external devices are available in the market.
There are various types of USB adapters, many of which do not require a power supply, are compact and low-cost.
In the video signal (NTSC method), the total number of scan lines is 525.
When converted to USB, the resolution is generally 640×480 (about 300,000 pixels).
Modern USB cameras have a standard resolution in megapixels, and the video signal resolution is a bit lower than these.
However, its fast frame rate and small data size make it a good choice for recording videos.
This microscope is a type that connects directly to a TV monitor via a video cable.
Video cable |
If your TV uses a BNC terminal, we provide you with the appropriate conversion adapter. |
The advantages of this microscope include smoother movement and delay-free display compared to those with a USB connection, which improves visual comfort and is suitable for inspections, etc.
In addition, it is ideal if you want to record videos for a long time, and if you use an HDD recorder, you can record for 24 hours.
On the other hand, the disadvantage is that the resolution is relatively low, but a high-resolution full high-definition microscope is also available. Additional hardware is required to store images, such as a video recorder that supports USB sticks. However, it also has the advantage of being able to use a lot of external equipment, since the video signal is common. It is also possible to transfer images to a PC using USB Video Capture, but the image quality may be reduced.

Various video microscopes |
※In addition, we have a variety of microscopes, including high magnification and low magnification. For more information, please contact Technical Support.
Our USB microscopes are not compatible with tablet-specific operating systems (e.g., Windows RT). Therefore, it is necessary to check the OS before use.
In addition, please note that it is not compatible with Mac systems.
■General-purpose type

|
 |
Lenovo ThinkPad OS：Windows 10 Pro（32bit） CPU：Intel Atom Z2760 Main memory capacity：2GB |
 |
USB port：A port |
There may be a delay in the display of the video, which may not be suitable for practical use. This delay can be attributed to the CPU’s processing speed, memory, and bitness.
In general, it is said that “Windows 10 needs 64 bits and 8 GB or more of memory to run smoothly”. Some standard models of tablets may lack performance.
■ High-performance machine type
 |
SurfacePro OS：Windows 10 Pro（64bit） CPU：Intel Core i5 Main memory capacity：8GB |

The video is displayed normally, and the display speed is at a level that is not a problem in actual use. After installing a 300M camera, there will be no problems in its use.
However, if you use a tablet, the display speed can be very slow, so you need to check. We recommend a type that has a “USB-A port” with “Windows 10”, “64-bit”, and “main memory capacity of 8GB or more” and can connect the camera directly.
This article discusses errors that occur when a PC fails to recognize a camera.
If this errors appear when the PC is unable to detect a camera, primarily due to three reasons:
1. The camera is not connected to the PC or is not directly connected.
2. The camera’s driver software is not installed.
3. Another camera’s driver, such as one for a built-in PC camera, is being used.
<Solutions>
Please choose Option → Select Device.
The Select Device screen will open.
Please select the camera you are using.
(If the camera in use does not appear in the window)
There’s a possibility that the driver is not installed, so please proceed with the installation of the driver software.
Some USB cameras themselves have an edge enhancement function, but this time I will introduce an image processing method.
There is a technique called Unsharp Mask (USM).
PhotoShop and others also have this function, but there are other software that also has this function.
USM is a type of filter that emphasizes the difference in color between the pixels that make up an image。
Before applying Unsharp Mask
After applying Unsharp Mask
Sharpen images that look blurry throughout.
It is a filter that has the function of highlighting the contours of the image.
In addition, our real-time image processing software REAL Effect allows you to view the image in real time and apply contour enhancement to the required level.
We would like to introduce the height measurement (Z-axis measurement) system.1. System configurationInstall the Z-axis stage and motor controller on the microscope. |
|
 |
 |
| We use this system, Mitani Shoji’s focus synthesis software, and 3D creation software. | |
2. How to operate |
|
| (1) Focal stacking | |
 |
|
| (2) Create a 3D image | |
| (2) Create a 3D image: Combine the photo synthesized with a microscope with the position information of the motor to create a 3D image. | |
 |
|
 |
 |
|
From the microscope, you can’t see a vertical or near-vertical surface, so the wall surface is a little more stable, but height measurement can be done without any problems. If there is a slope on the wall, a relatively clean 3D image can be created. As an example, make a 3D image of a dent in a cardboard box. |
|
 |
|
| From here, arbitrary dimensions and cross-sectional shapes can be determined. The yellow line below is an arbitrary line.
|
|
 |
|
 |
|
| Since it is not a measuring machine, there is no accuracy. The smallest step in the Z-axis table (0.5 μ in this case) is the resolution. Depending on how you use it, you can achieve a certain degree of accuracy. |
|
There are various free and paid options available for interval shooting.
Our Viewer software, “Measure,” also offers this functionality, but it has limitations with a maximum interval time of 100 seconds and a cap of 999 shots.
Additionally, we provide extra software that allows for unlimited shots and extended interval shooting durations.

Such software could be beneficial for time-lapse photography using microscopes, such as for bacterial, tissue, or microbial cultures.
Welding is used in the metal joining process, and the welded area is crucial for product safety. Therefore, inspections such as measuring fusion volume are conducted. The dimensions of fusion are measured on cross-sections to inspect for insufficient fusion, welding defects, clearances, excess fusion, and more.
Inspection of fusion in the welded area requires the following preparation:
①Cutting the test part.
②Polishing the cross-section.
③Etching treatment using chemicals or electrolysis, depending on the material.
These preparations are done to facilitate observation and dimension measurement. Leave these pre-treatments to the experts, and we will introduce the perfect product for measuring weld fusion volume.
We promptly captured and measured with our microscope.
This involves:
・Generating reference lines
・Measuring distances from the intersection of reference lines
・Creating parallel lines
・Measuring perpendicular distances from reference lines
Repeating these steps can be time-consuming, especially with a large number of samples.
With our measurement software, we offer features that assist in such measurements, reducing inspection time and streamlining the process of measuring weld fusion volume.
By clicking anywhere on the screen with the mouse, you can generate crosslines. If there is any misalignment, you can easily adjust the line position by clicking again.
 |
You can also change the color and line width. |
There are various measurement items available, which can be used for actual measurements as well as reference lines. When used as reference lines, you can turn off the measurement value display. In particular, ‘Vertical Distance’ was quite useful in this case. Additionally, you can change the display color for each measurement line and value individually.
 |
●Two-Point Distance |
When you move the mouse cursor close to the line you want to measure, it automatically fits to the edge. This reduces human errors by the operator and allows for accurate measurements.
By scrolling the mouse wheel, you can zoom in or out digitally with the cursor point as the center. This further reduces human errors by the operator. It’s an intuitive feature that allows easy zooming and is very convenient.
You can display the scale at any desired location with the size you want.
With a single click on the Excel output button, measurement data is transferred to Excel. This allows easy data processing and graph display in Excel. Raw images, images with measurements and lines, and measurement values are all exported to Excel in one click, saving time in report creation. It’s a highly convenient feature.

When it comes to creating lines within images for alignment or using them as reference lines, many of you may be aware that it can be done with a line generator. However, in the end, preparing a separate line generator in addition to the camera and lens can unexpectedly increase the cost.
The camera we use in our high-definition microscope already has this line generation feature as a standard. Therefore, you can easily and affordably generate lines without any additional expenses.
Each camera in the High-Definition Microscope comes standard with a crossline display function. In this case, a separate line generator is not needed, and crosslines or crosslines at any desired position can be generated using only the functions of each camera.
We will introduce each camera individually.
① HIGH-PERFORMANCE FULL HD (HIGH-DEFINITION) CAMERA XM200HD
 |
|
For the XM200HD, it generates a center crossline in the middle of the screen. The line color is red, and you can’t change the color of it. You can toggle the line display on and off.
Microscopes using the XM200HD include:
・High-Function High-Definition Microscope TG200XM
・High-Function High-Magnification High-Definition Microscope FZ200XM
・High-Function Low-Magnification High-Definition Microscope LRS200XM-MC1
・High-Function Long-Distance High-Definition Microscope (Stand Type) LRA200XM-S
・High-Function Long-Distance High-Definition Microscope (Edge-Fixed Type) LRA200XM-E
・High-Function Coaxial Illumination High-Definition Microscope Z200XM
 |
|
For the GR200HD2-MePRO, it’s a high-definition camera with line generation capabilities (custom crosslines, concentric circles, angle lines) and measurement functions. Line generation is possible at any position, including concentric circles and angle lines. You can choose from 5 different line colors. This model also comes with measurement capabilities.
Microscopes using the GR200HD2-MePRO include:
・Multi-Function Hybrid Microscope TG200HD2-MePRO
・High-Magnification Multi-Function Hybrid Microscope FZ200HD3-MePRO
 |
|
For the BA200HD, it’s a high-definition camera with both custom line generation and crossline generation capabilities. Line generation is possible at any position, and you can also generate a center crossline in the middle of the screen. You have the option to choose from 5 different line colors. It can generate up to 4 vertical and 4 horizontal lines.
Microscopes using the BA200HD include:
・Low-Cost High-Definition Microscope TG200BA
・High-Magnification Low-Cost High-Definition Microscope FZ200BA
In the case of a USB microscope camera, you can use the optional viewer software (MF Ship) to display multiple crosslines.
|
|
As for video microscopes, a line generator is required.
In our company, we also sell a line generator (USB memory-compatible video recorder with split function) GRAV-1.
 |
|
Optional line generation capabilities, dual-screen display (left/right or top/bottom), still image and video capture, and external trigger-compatible line generators are also available.
With this setup, positioning and alignment with two cameras becomes effortless.
In summary, there are numerous high-definition cameras (microscopes) available that integrate a camera with a line generator for tasks like alignment. You can choose the one that best suits your needs.
As an extra, there are methods involving USB cameras and software, as well as methods using video cameras and line generators.
One cause may be insufficient current supply from the PC.
(This is not noise, etc., and cannot be handled by repeater cables, etc.)
Notebook PCs in particular may have a low total power supply or be in power-saving mode by default.
In this case, a simple solution is to use a self-powered HUB (HUB with AC adapter).
This will ensure that the power supplied to the camera and active cables comes from the HUB and not from the PC.
Translated with DeepL.com (free version)
Self-powered HUBs with ammeter are also available as shown below.
A video in which still images taken at intervals are stitched together in succession is called time-lapse, and is also described as time-lapse shooting.
It is the exact opposite of a video shot with a high-speed camera (slow-motion video), and is a long shot video played back in a short time.
Therefore, unlike long-term video shooting, it is possible to shoot for a long time with a small capacity.
In addition, since each image is a still image, it is possible to shoot with high resolution.
Shooting a time-lapse video is easy without any specialized equipment.
(1) Many cameras have a time-lapse shooting function, which makes it easy to shoot.
(2) You can also drop the time-lapse compatible app and shoot with your smartphone.
(3) Take interval shots and save still images. Use editing software to make a time-lapse video.
When using our products, the method (3) above is used.
In order to take interval shots with our USB camera, we use our dedicated software Hi TriggerQ to take a picture of the object and save a large number of still images.
|
|
First, I tried taking interval shots of the company with the above software.
This is concatenated using editing software to make a video.
There are editing software such as Windows Live MoveMaker, but this time I tried using the free software “Panolapse”.
The free version has a limited resolution, so I dropped the resolution of still images.
(The restriction will be lifted when you purchase a license.)
It will be downloaded in the following format.
When you launch Panolapse .exe, the following screen will start.
Click “Import to Panolapse” to import all the still images taken at intervals earlier.
That’s all you need to do to get a time-lapse video when you click on the preview button.
※Note※
Time-lapse editing software is not our product.
This is an example of this.

When employing high-magnification instruments such as microscopes to project images, areas of focus and defocus can occur if the subject is not perfectly flat. This phenomenon can be mitigated by employing focus stacking, which enables the creation of an image with uniform focus.
Focus stacking is a technique that combines multiple images, each with different focal points, to produce a single image where everything is in focus.
This process can be efficiently executed using our measurement software, MFShip.
|
High-Performance Image Processing Measurement Software MFShip
|
MFShip is a sophisticated image processing and measurement software that offers two methods of focus stacking.
The first method involves selecting and combining already captured images, while the second method, a recommended feature of the software, is known as “rotational synthesis.”
Rotational synthesis is a feature that allows for the instantaneous creation of composite images from real-time video.
As illustrated in the provided photograph, composite images can be created instantaneously. If you are experiencing difficulties with adjusting focus on your subject, we highly recommend giving this method a try.
Shodensha Vietnam is pleased to announce our schedule of Tet Holiday as follow:
– Our office will be closed from Thursday, 8th February 2024 to Wednesday, 14th February 2024
– Business operation will resume as normal on Thursday, 15th February 2024
We would like to take this opportunity to thank you for your continuous support.
(1) Simply use multiple launches of Viewer software that can be started at the same time.
(2) Use software dedicated to multi-screen display.
It may also be possible with free software.
However, it may not be possible to do it with the same camera, and stability is lacking.
We recommend that you always try it before using it.
(Depending on the software, multiple activation itself may be prohibited.)
The following is a simple trial at our company. (Operation is not guaranteed.)
I connected two of our cameras and started multiple free software called Amcap to display two screens.
 |
 |
In the case of a two-screen display, you can only operate the active screen (left screen above), so if you want to operate the menu, you need to switch screens.
Since it is software for the purpose of displaying multiple screens, it is stable.
In addition, since there is only one menu, operations such as saving are easy.
The following is a multi-screen display software produced by our company.
 With a 3 million pixel color camera Example of simultaneous use of a 1.3 million pixel monochrome camera |

You can control multiple cameras, observe both screens, and save images.
In addition to cameras with the same model number, different resolutions and combinations of color and monochrome cameras are also possible.
Of course, you can also use it with one camera!
● Save still images (uncompressed bitmap format / JPEG compressed format) of up to 4 cameras with a trigger signal while live monitoring the video. (Please contact us if you would like more than 5 units.) ）
● The image of the camera is always displayed live. You can shoot while monitoring the video.
● Snapshot function that allows you to take still images at any time
Regardless of the trigger signal, it can also be left in a still image with a mouse click.
You can save a still image on the spot at any time, such as a reference image or a scene of interest.
● Interval shooting is possible.

「Even if the camera does not have an external trigger terminal, we sometimes receive requests from customers who want to save images using an external trigger.
In such a case, why not use a ready-made input box?
Shodensha’s Viewer software Measure has several shortcut keys.
For example, “Save” is set to “Ctrl+S”.
Using the ready-made input Box, you can convert the signal from the external switch (external trigger) into a key signal such as “Ctrl+S”. In other words, instead of pressing “Ctrl+S” on the keyboard, you can save the image being displayed in the Viewer software Measure by turning on the external switch.
This time, I tried using “Anything Switch USB” (made by Techno Tool Co., Ltd.) as a ready-made input box.
The setting method is as follows.
1. Connect an external switch to the terminal of the input box.
2. Connect this input box to a computer via USB.
3. Install the software that came with the input box on your computer.
4. With the included software, give meaning to the external switch connected to the 1~5 terminals.
For example, if you set “Ctrl+S” above as the output when the switch is on, you can save the image at any time using an external trigger.
This completes the configuration.
After that, if you turn on the external switch at any time while displaying the image with the Viewer software Measure, you can easily import the image even if the camera does not have an external trigger terminal.
It’s easy to set up, so it’s worth a try.
Depending on the metal material, its mechanical properties (resistance to external forces such as tensile and compressive shear)
The properties of the material are different, and it is necessary to use the metal material according to the application.
In addition, heat treatment changes the metallographic structure and its mechanical properties.
Therefore, this grain size analysis is an important test for product quality assurance.
(1) Visual comparison between standard drawings and metallurgical microscopes (comparative method)
(2) Simultaneous observation and comparison of eyepiece micrometers incorporated into a metallurgical microscope (comparative method)
(3) Incorporate an eyepiece micrometer into a metallurgical microscope and calculate it by simultaneous observation and comparison (cutting method)
(4) Using a camera, there are generally four patterns of soft particle size measurement (counting/quadrature method, cutting method).
Although it is the method (4) above, crystal grain size measurement can be performed automatically with software, and efficiency can be improved.

This is a measurement method by visual inspection. Place a sample of metallographic structure under a microscope,
“Microscopic observation” and “Standard drawing of grain size (×100) JIS G 0551” and “Printed standard drawing”
Compare with an eyepiece micrometer (reticle).
This is the method of obtaining the grain size from the nearest standard diagram.
With this software, you can simply select a standard diagram while observing the microscope camera image in real time.
Calculate the grain size. Microscope camera images are superimposed on standard drawings in real time.
It is a useful feature.
The cutting method is to write a pattern (test line) on the captured microscope image, and then
The average line segment length per grain when the pattern crosses the grain is determined, and the grain size is
This is how it is calculated.
< Measurement display example>ASTM (intersection cutting method, section length comparison method)
After measurement, the display shows in blue where the grain boundary rests on the cutting pattern.
* The image example measures a microscope magnification of 100x and a range of 1000 x 1000 dots.
If you have a lot of grain size measurement, this grain size measurement software has a convenient function
The trick to saving labor is to use it and measure automatically.
1. Observation by the sump method using transmitted illumination with a microscope

Therefore, we will introduce the sump method.
What is the < Sump Method? >
There is a method called the “sump method” (*1), in which the structure of the surface of the object to be observed is copied to a very detailed part as if it were a mold, and the copied object is observed. It is ideal for observing objects that do not allow light to pass through, such as the stomata of plant leaves and the cuticles of hair.

It is possible to see the cuticle of the hair even with a metallurgical microscope.
However, metallurgical microscopes are large with a body size of 203 x 255 x 421 (H) mm.
The appearance differs depending on the model and method, so please contact technical support for details.
When looking at metal surfaces with a microscope, it is common to observe with a set of ultra-high magnification microscopes and coaxial illumination.
However, when it comes to observing metals, there is a microscope called a metallurgical microscope that specializes in this field, and there is also a method of observing by attaching a camera to it.
(The main body size of the metallurgical microscope is as large as 203 x 255 x 421 (H) mm.)

According to the USB 2.0 standard, it is limited to 5 m.
In fact, cables that exceed this are sold by major manufacturers.
(It is said that up to about 10 m, it does not affect the communication speed much.)
Not only extension cables, but also the following are also sold.
It is a “USB cable with repeater function”. (It is also called an active cable.)
It is sold by multiple companies, but the product in the photo is
This is Sanwa Supply Co., Ltd.’s KB-USB-R212 [12m Extension USB Active Repeater Cable].
According to the USB cable standard, the maximum length of the cable is 5 m between devices.
However, by using this “USB cable with repeater function”, you can connect devices with a cable of 5 m or more.
For the product in the picture, this cable alone can be extended by 12m.
This cable has a built-in signal amplification correction circuit. By restoring the attenuated signal in this circuit, it is possible to extend the cable.
The cable can also be extended to more than 12 meters. In that case, wire as follows.
I connected a 12m USB cable with repeater function (product in the photo) and the cable included with the camera (1 .8m) to our USB camera, and it worked without problems. However, in the instruction manual of the USB cable with repeater function (product in the photo), there was a sentence that said, “In order to ensure stable operation and recognition, it is recommended that the USB device to be connected is a device that operates on its own power.”
Of course, there are also active cables that use USB power (bus-powered).
It is easy to use without the need for a power supply. However, if your PC’s power supply is vulnerable, it can become unstable.
If the USB cable is extended, a voltage drop will occur, so it is recommended that devices (including our USB cameras) that operate by power supply from a PC be sure to check the operation before using it.
The microscope connects to the computer using a USB cable and displays an enlarged image on the screen.
The advantage is that it can be viewed with a computer and the image can be saved simply. Furthermore, using the software, you can perform a variety of tasks including image processing such as measurement, focus synthesis, and binarization.
Furthermore, most of the cameras used in our microscopes USB are Directshow compatible cameras, so you can also use Directshow compatible software from other companies.
The downside is there
The downside is that there are some errors due to USB specifications and the display speed becomes slower corresponding to the resolution of the camera used.
Microscope
We recommend microscope USB3.0 for USB type because the disadvantages of microscope USB3.0 have been significantly reduced compared to USB2.0.
At our company, there are many types of microscopes USB available.

Regular USB3.0 is different from USB 2.0
・Transfer speed：500MB/s
・Compatible or higher with USB2.0
・Maximum cable length 3ｍ
Only the basic parts are shown.
Of these, USB3 Vision was created as a “camera interface standard using USB3.0” that can be reliably used for commercial, industrial, and machine vision applications.
Stability
・High-speed data transmission
・Transmit data accurately
・Stable recovery from error transmission state
Reliability (compared to connector)
・Check and verify accuracy
・Fix firmly to the outside part
Was created with a purpose
Has the function of resending packets when a transmission error (packet drop) occurs.
→This will virtually eliminate screen freezes that occur with USB2.0.).
If the image is saved “from camera → via CPU → memory”, it is called “camera → memory”.
→ Can reduce CPU load.
(Depending on the manufacturer, it is expressed differently, such as “direct memory access,” “no-copy mechanism,” or “DMA.”)
Furthermore, the connector is also used with a screw locking function
Compared to GigE cameras, stability and speed are quite similar.
It has the disadvantage of a maximum cable length of 3m, but recently machine vision cables using fiber optic cables have been introduced and they can be used in lengths of 10m or more.
Cameras that comply with this standard are marked with the USB3 Vision logo.
Our USB camera CS series and GigE EG camera series are equipped with external signal input so that images can be saved from external signals.
（Optional trigger cable is required for signal input.）
However, the standard software does not have the function to save from an external signal, so you will need to use optional software or create a program using the included SDK.
There are two main types of optional software that save still images by inputting an external signal.
The main difference is between types that always display a live image while waiting for an external signal and types that do not display a live image while waiting for an external signal but instead display a stored static image with the most recent signal.
The advantage of continuous live display is that images can be viewed at all times. On the contrary, saved images cannot be checked unless you access the save folder.
HiTriggerQ continuous live display type
The advantage of displaying a still image saved using the most recent signal is that you can always check whether the image has been saved correctly.
On the contrary, if you want to watch live video, you need to cancel the state of waiting for external signals.
Still image storage type is saved with the most recent signal HiTriggerF Pro
If you want to program it, please use the SDK located in the camera’s driver installation folder.
If you want to save images using an external trigger on a camera without an external signal input, you can also use a ready-made input box, etc. to call up an external software shortcut and save the image image.
There are many types of metals and it is necessary to choose the right metal material according to its use and purpose.
For example, automobile engine parts and general metal parts use different metal materials.
This is because mechanical properties (such as strength against external forces such as tension and shear) vary greatly depending on the metal material.
To evaluate this metal property, it is necessary to observe the crystal structure of the metal structure.
The metallic structure is a polycrystalline structure with a crystalline structure consisting of crystalline grains.
In the space between crystal grain and crystal grain there are disordered patches and the boundaries of those patches are grain boundaries.
The granularity of this crystal grain (crystal grain degree) is an important factor that determines the mechanical properties of that metal material.
In general, crystallinity refers to the “magnitude of crystal grains” in materials such as metals.
Furthermore, metal structure changes not only by the type of metal material such as aluminum, iron and alloys but also by heat treatment.
Even when the metal or alloy is of the same type, heat treatment will cause the crystalline grains to align in a specific pattern, forming grain boundaries that are different from those before heat treatment.
Therefore, heat treatment changes the grain size and changes the mechanical properties and properties of the metal.
Therefore, grain size analysis is an important test to ensure metal product quality.
・Austenitic granules
Consists of twin crystals annealed in the crystal grains of the central face of the cube
・Ferrite beads
Does not include twin crystals annealing in the rim line of the centrosomal face
We perform pretreatment such as polishing the metal surface and observe it with a metallurgical microscope.
Grain size was estimated by visually comparing the metal structure magnified by a metallurgical microscope with the “Austenite Grain Size Standard Diagram for Steel (x100) JIS G 0551”.

However, you have to take your eyes off the metallurgical microscope for a while, which is troublesome.
Insert an eyepiece micrometer (reticle) with printed grain size sample into the eyepiece of the metallurgical microscope, and visually observe and compare the enlarged sample and the grain size standard sample to determine the grain size .
This is easy because you can simultaneously observe and compare without taking your eyes off the metallurgical microscope.

【Can measure up to 12 types of particle sizes!】 ・The evaluation method is to perform up to 12 measurements at the same time by combining the cut samples and calculating the number of grain sizes. 【Cutting pattern can be selected from 5 types!】 ・For cutting method, you can choose from 5 cutting patterns and set spacing and line length.
【Useful for making reports! Excel Output】 ・Particle size measurement results can be exported to Excel (CSV format).
ASTM (intersection cutting method, intersection length comparison method) In the display after measurement, areas with grain boundaries overlapping the cut sample are displayed in blue. *Image example is a 1000×1000 point scope measurement with 100x microscope magnification. |
If particle size analysis is not routine, using an eyepiece micrometer is a cost-effective method.
If you do this regularly, there will be initial costs, but we recommend using a microscope camera to automate measurements with software, as it automates and saves labor.
The software also has other useful functions.
