RELATIONSHIP BETWEEN DEPTH OF FIELD AND OPERATIONAL DISTANCE

To increase the depth of field, there are two typical methods below

(1) Increase depth of field.

(2) Narrow the optical path

 

This time we will explain about (1)

■Relationship between depth of field and operating distance

Below is a table of specifications for lenses from the same manufacturer, same series, and same magnification (X4).

W.D. The longer it is, the deeper the depth of field.

 

レンズのスペック表

 

 

■Measure the actual depth of field thanks to the difference in operating distance

Tilt the 0.2mm pitch glass scale at 45° and observe it from above.
Comparative shooting with lenses from the same manufacturer and lens series with different operating distances.

 

 

真上からから観察

 

 

(1) Observe with x6 optical magnification lens with operating distance of 40mm

 

作動距離40mmのレンズで観察

 

If we judge that the focus is on a scale (0.2 mm), then the depth of field is 0.2 mm x (1/1.41) = 0.14 mm.

 

 

(2) Confirm with a lens with optical magnification X6 and operating distance of 110mm

 

110mmのレンズで確認

 

If we judge that the focus is on two scales (0.4 mm), then the depth of field is 0.4 mm x (1/1.41) = 0.28 mm.

 

PHOTO STAND (COPY STAND)

When using a digital camera to photograph paper materials, books, or other three-dimensional objects that cannot be copied, it is convenient to have a copy stand.

There are various sizes and prices on the market, but the ones below are relatively affordable and allow you to take photos up to A4 size.
The size is 450x450mm and the pillar height is 550mm.

HOW TO USE A HANDLE MICROSCOPE

When using a handheld microscope, there are 3 following vital notes: 

1. Display speed

When taking pictures with a handle microscope, the screen inevitably shakes.
If the display speed is slow, the “shaking” phenomenon will not stop.

2. Power source

A microscope needs two power sources: the camera and the light source.
Dedicated machines may be provided with a USB port.

3. Adjust brightness

Since one hand is busy, I think it would be easier to use if there was an automatic exposure mode.

DinoLight products are available as special handheld machines with a wide range of products and low prices.

Depending on the combination, some of our products can also be used as hand tools (Since this is a combination product, it is not listed in the catalog as a set, so please contact us.)

・1.3 million pixel USB3.0 camera (global shutter USB3.0 camera with fast display speed)
・Low magnification SG2 lens (small, small diameter lens for ergonomic users) 
・16-light ring light (can be directly connected to the lens and powered by a PC USB port)

 

Dimensions as shown below

 

 

Both the camera and light can be powered from a PC. (No separate power supply required.)

Is image processing necessary as pre-processing for image testing?

● Issues with Automated Visual Inspection

In recent times, many users have incorporated automated visual inspection using image-based methods.

  • Pixel-check type automated visual inspection,
  • Pattern-check type automated visual inspection
  • Automated visual inspection with AI embedded in the above types.

While there are various methods, some users encounter challenges where the automated visual inspection fails to detect and overlooks instances marked as “NG” (Not Good). Upon investigation, it is often found that the NG elements are not clearly visible in the inspection images.

● Necessity of Image Processing

In such cases, reconsideration and reconstruction of hardware elements such as:

  • Camera resolution
  • Camera performance
  • Lens performance and magnification
  • Illumination methods are often required. However, even after revising the hardware, successful detection can be challenging.

As mentioned earlier, the fundamental principle is that even humans, software, or AI cannot detect what is not visible. In fact, at this point, software and AI may be inferior to humans. In such instances, there arises a need for image processing as a preprocessing step.

Instead of directly streaming raw acquired images to the inspection software, it is preferable to apply image processing as a preprocessing step before streaming the processed images to the inspection software. While this may increase tact time (inspection time), it is an effective method when detection without preprocessing is challenging.

● Types of Image Processing

Image processing includes various techniques such as binarization, contrast correction, brightness correction, color correction, color limitation, smoothing, edge enhancement, contour enhancement, noise reduction, sharpening, and, in a broader sense, resizing, measurement, line generation, and more.

● How is Image Processing Performed?

Typically, static images are saved, and image processing is carried out using an image processing unit.

● Can Image Processing be Done in Live View (Real-Time)?

The answer is yes. If the microscope’s display software has image processing options in the view function, you can perform image processing in real-time during live view and then save the static image. However, such capabilities are often found in high-end microscopes, requiring a substantial investment.

CHECKING VISUALITY WITH A MICROSCOPE

CHECKING VISUALITY WITH A MICROSCOPE

Many of the examinations performed using a microscope on the inspection line are extremely tiring and place a significant burden on the examiner. Therefore, many people are thinking about replacing it with a small microscope. However, there are many types of microscopes and if you don’t choose the best one, you may be creating an unnecessary burden on yourself.
There are three points to keep in mind when replacing a microscope with a mini microscope:

THREE IMPORTANT POINTS FOR REPLACEMENT

① CHOOSE A MODEL WITH A HIGH FRAME RATE

The microscope displays images on a PC or monitor.
If the frame rate is low, the projected image will not move smoothly, causing additional tension.
Frame rate is expressed as a number, but the number that makes people feel uncomfortable is around 50 to 60 fps.
When the speed drops below 30fps, the feeling of discomfort becomes noticeable.
PC-connectable models often have low frame rates due to USB communication speed issues.
Therefore, we recommend that you choose the screen direct connection type.

②Choose a model with good color reproduction

The appearance will vary depending on the camera used for the microscope.
For this reason, there are some items with good color reproduction and others with not so good.
If the colors don’t look good, the human brain will feel uncomfortable and this will lead to stress.
Even if a red object looks slightly orange, it can make you feel uncomfortable and stressed.
If you choose a camera with full resolution, the color reproduction is relatively high, so you can get clear images.

③SELECT A MODEL WITH WIDE DYNAMIC RANGE

I don’t think you’ve heard the term dynamic range often.
Briefly explained, when you illuminate a bright object and a dark object at the same time, if you adjust the brightness of one object, the other object may appear blown out or dim.
To eliminate this phenomenon, a camera with a wide dynamic range is needed.
Dynamic range is a state that a camera has but it also varies depending on the camera.
Compared to conventional cameras, the human eye is very good and has a very wide dynamic range.
The main reason why things look different to the human eye and through a camera is often due to differences in dynamic range.
There are models that emphasize wide dynamic range, so I think it’s best to choose one of those.

THE RECOMMENDED MODEL IS:

We also have car models that meet all 3 points above.
Full high definition microscope
Frame rate = 60fps
Color reproduction = Very clear resolution thanks to full high definition resolution
Dynamic range: Wide with HDR function (high dynamic range)
We also have demo machines, welcome to try them out.

THE POOR REPRODUCIBILITY OF THE PRINTER

There may be instances where the captured images cannot be printed with the desired color reproducibility.

When the resolution of the captured images is sufficient, the printer’s performance may be influencing the outcome.

<USING GENUINE PAPER>

Using genuine paper from the printer manufacturer or paper closely resembling to them.

<USING A 6-COLOR TYPE (OR MORE)>

Color printers cannot reproduce colors lighter than the set ink colors. Equipping the printer with lighter colors such as light cyan, light magenta, gray, etc., allows for subtle adjustments in color variations. While standard printers often have 4 colors, it is advisable to use 6 colors (or more) when printing images.

<USING A HIGH QUALITY PRINTER TO PRINT PHOTOS>

If you use a high-quality photo printer like the one below, the quality of your printed images will be improved.

ABOUT SURGE COUNTERMEASURE

Surges, stemming from various factors, refer to abnormal voltages and the resulting abnormal currents.

Causes include “lightning surges” induced by lightning and “switching surges” resulting from the ON/OFF of the power supply.

Concerning “lightning surges,” power companies and communication providers implement diverse countermeasures, and specific surge-protective devices, such as surge tables, are available for purchase.

 

雷サージ用のテーブルタップ

 

“Switching surges” pertain to surges occurring during circuit opening and closing. Caution is advised when large-capacity motors, generators, high-voltage circuits, solenoids, etc., are connected to the same power line.

f power supply circuits frequently experience damage, abnormal operations occur, or similar issues arise, surge protection may be necessary. Separating power lines can be a straightforward solution, and various surge protection devices are also available for purchase.

MICROSCOPE USING A SINGLE-LENS REFLEX CAMERA

Combining a step-down ring with Nikon’s telephoto lens (f = 300mm), attach an M26 microscope objective lens to the end.

It is worth noting that this method is applicable even with standard lenses (approximately f = 50mm). While the magnification decreases, it is adequately accommodated with ring illumination.

 

標準レンズ(f=50mm程度)でもこの方法は使えます

The focal length is around 40mm, shorter than that of a dedicated microscope.

LONG DISTANCE SHOOTING / ZOOM IN WITH A SINGLE – LENS REFLECT CAMERA

The method to connect SLR lenses to camera C for long-distance and magnified photography involves the relatively straightforward application of a C-mount to F-mount adapter.

Therefore, even when observing at the same magnification, the same vertical calibration value cannot be used. When measuring by oblique observation, it is necessary to correct for such conditions.

 

Summary

 

For accurate measurements by oblique observation, calibration must be performed with the microscope tilted at a 45 degree. However, if you are tilting two axes (tilting not only left and right but also toward you), you need to consider both axes when calibrating.

For details on the “3D arm” and “measuring software” used in this measurement, please see below pictures.

UTILIZING THE LENGTH MEASUREMENT FUNCTION OF A MICROSCOPE FOR QUALITY CONTROL

In this article, we shall present the “Points to Consider,” “Usage Guidelines,” and “Recommended Microscopes” when utilizing the length measurement function of microscopes for quality control.

POINTS TO CONSIDER

While some microscopes have the capability to measure length, two operational issues may arise:

(1) The microscope itself is not a traceable measuring instrument.

(2) Calibration, except for some high-end models, must be performed by the user. (Errors may occur due to user operations.)

USAGE GUIDELINES

When used for quality control purposes, there is no issue with internal calibration. However, clarification is needed regarding the standards used in internal calibration. In other words, implementation is feasible if we can meet the following three conditions:

  • Using a microscope with reproducibility capability.
  • The reference device used to check the accuracy of the microscope is transparent.
  • Standards with traceable capabilities are available.

We have customers who have obtained ISO9001 certification and continue to use our products.

RECOMMENDED MICROSCOPES

When utilizing the length measurement function of microscopes for quality control, we recommend the following:

 

Microscope model CT200HD:

 

 

◆ Rare in the mid-range product line. Lens-camera interlocking system

The camera collects data from the lens and automatically utilizes the calibration data stored in the camera’s internal memory:

・ No adjustment required by end-users.

・ Values remain unchanged regardless of end-user operations.

◆ Providing special options with accurate measurement scale

May include calibration certificate and test results table for accurate measurement scale. (Charges)

OBSERVING BURRS INSIDE A HOLE USING TRANSMITTED ILLUMINATION METHOD.

Utilizing transmitted illumination to observe burrs and foreign objects within apertures.

We often receive requests to inspect burrs and foreign objects inside holes using transmitted illumination.

When the target object has a certain “thickness,” a bit of technique is required.

We conducted an examination by creating a hole with a diameter of φ5mm in a 12mm-thick aluminum plate and capturing images.

 

 

穴の中のバリや異物を観察

 

The upper, middle, and bottom surfaces in the above image have foreign objects adhered to them.

 

トップ(表面)、ミドル(中間)、ボトム(底面近く)

 

 

To detect all of these, the use of a lens with aperture control is necessary.

 

 

 

トップの焦点を合わせる

 

ミドルに焦点を合わせる

 

 

■ When using an open-aperture lens

Observing the top surface with the lens opened and focused yields the following results.

 

開放レンズを使った場合

* The middle and bottom become nearly imperceptible.

When focusing on the middle using an open-aperture lens for observation, the results are as follows.

 
 

 

開放レンズで中間に焦点を合わせ観察すると下記のようになります

*The top is visible but appears slender, while the bottom is in a highly indistinct state.

 

■When employing a macro lens with aperture control…

絞り付きのマクロレンズを使った場合

 

Capture the image with the aperture narrowed as much as possible.
  (Compensate for the resulting darkness with additional illumination, and keep the camera gain around 90% rather than at its maximum.)

 

*Both the top (surface) and middle (interior) as well as the bottom (near the base) can be adequately observed.

 

トップ(表面)・ミドル(中間)もボトム(底面近く)ともに十分に観察できます。

 

  • In conclusion,

To observe burrs and foreign objects within the hole, it is essential not only to use transmitted illumination but also a lens with aperture control that can deepen the depth of field.

“SUITABLE MICROSCOPES” AND “UNSUITABLE MICROSCOPES” FOR DIMENSION MEASUREMENT

Many microscopes on the market have a size measurement function. However, some types are still difficult to use. When using the measuring function, a microscope can be said to be suitable for measuring dimensions if it has the following two characteristics:

(1) Zoom lens.

(2) Latching function.

Below we will introduce each characteristics in detail.

(1) Zoom lens:

There are two types of lenses that can continuously change magnification:

  • “Variable magnification lenses” are not suitable for measuring because the focal length changes significantly when magnification is changed.
  • “Zoom lens” are suitable for measuring because the focal length remains almost the same even when magnification is changed.
(Maximum magnifiaction)  

(Minimum magnifiaction)

<Suitable for measurement> Zoom lenses (except our SG series)

(Maximum magnifiaction)   (Minimum magnification)
寸法測定に向き・不向きマイクルスコープ03   寸法測定に向き・不向きマイクルスコープ04

(2) Latching function:

When measuring dimensions, the ability to reproduce conditions is important. If the optical magnification (scale) is marked on the lens and each scale has a latching function, inter-operator variation is eliminated and reproducibility is maintained.

 

<Not suitable for measurement> Products without latching function

 

Low-cost microscope series (sG series)

<Suitable for measurement> All other product lines have latching function.

寸法測定に向き・不向きマイクルスコープ07

 

(Note) If you want to measure with a low magnification microscope as mentioned, our “low magnification microscope” (LRS series) is not suitable for size measurement (Because reproducibility cannot be achieved). Although the magnification cannot be lowered with the LRS series, if you attach the “0.5x auxiliary lens” to the TG series, it can be used as a low magnification microscope for reproduction.

Although the TG series could not achieve as low magnification as the LRS series, it can maintain a field of view as wide with two dimes and perform highly reproducible measurements.

 

寸法測定に向き・不向きマイクルスコープ10

 

 

LONG-RANGE (EXTENDED WORKING DISTANCE) MICROSCOPE

We occasionally receive requests expressing the desire to increase magnification with an extended working distance.

Typically, increasing magnification results in a shorter focal length.

Allow me to present options classified under the category of long-range types.

 

■ Long-Range (Extended Working Distance) Microscope (LRA Series)

 

Our extended working distance microscope not only incorporates a 10x zoom function but also achieves an extended working distance seamlessly.

The focal length can be adjusted freely within the range of 200 mm to 400 mm.

 

長距離(長作動)マイクロスコープ (LRAシリーズ)

 

(1) The field of view at maximum magnification when the focal length is set to 250 mm.

 

In the horizontal direction, it measures 6.7 mm, equivalent to an approximate magnification of 70 times.

(2) Resolution at Maximum Magnification with a Focal Length Set to 250 mm

 

The resolution, as reflected by a glass scale used for resolution checks, is as follows.

 

焦点距離を250mmに設定した時の最大倍率時の解像度

 

(3) Advantages and Disadvantages

 

While the presence of a 10x zoom function and the ability to vary magnification at the same distance represent significant advantages, there is a slight reduction in resolution.

The field of view at maximum magnification with a focal length set to 250mm→400mm is as follows.

 

メリットとデメリット

 

 

■ ƒ=75mm Fixed-Focus Lens Application

 

By adding a 2x rear converter and a 15mm close-up ring to a 75mm telephoto lens, it can serve as an alternative to the Long-Working Distance Microscope (LRA series).

 

f=75mm 固定焦点レンズの応用

 

(1) Field of View when the focal length is set to 250mm

Without a zoom function, once the focal length is decided, the magnification is determined. The horizontal field of view is 8mm, resulting in approximately 60x magnification.

 

焦点距離を250mmに設定した時の視野

 

 

(2) Resolution at maximum magnification when the focal length is set to 250mm

 

When projecting a glass scale for resolution checks, it appears as follows.

 

焦点距離を250mmに設定した時の最大倍率時の解像度

 

 

(3) Pros and Cons

 

While the focal length can be adjusted, once determined, it fixes the magnification as well. Without a zoom function, the lens has fewer elements, resulting in a brighter image and higher resolution compared to the aforementioned Long-Working Distance Microscope (LRA series).

In a direct comparison at maximum magnification, it slightly falls short compared to the Long-Working Distance Microscope (LRA series). The price is lower due to the absence of a zoom function.

When the focal length is set to 250mm→400mm, the field of view is as follows.

 

メリットとデメリット

 

 

■ High-Resolution, High-Magnification Zoom Lens

 

There are specialized lenses with high resolution, high magnification, and zoom functionality available through our products. For more details, please inquire.

It is capable of achieving 420x magnification at a focal length of 200mm.

How to observe polarized light with a microscope

When conducting polarized observation, the efficacy is heightened by incorporating polarization filters on both the emitting and incident light sides. Subsequently, the polarization intensity is adjusted by rotating either of the polarization filters.

 

 

Our company’s microscopes, specifically the TG and FZ series, are equipped to facilitate polarized observations by directly affixing light-emitting diodes (LEDs) to the lens.

<When diminishing magnification by attaching an auxiliary lens>

Due to the concurrent placement of auxiliary lenses and incident-side filters, their simultaneous attachment is precluded.

この異なった視野を観察者が一つの映像として観察します。
人間の目が2つあるのと同じです。

 

これによるメリットは、対象物が立体的に見えます。
遠近感もわかるので、加工作業をされる方は実体顕微鏡が必要です。
デメリットとして、使う時に少しコツが必要です。
(初めて使う方は、映像が1つにならず、戸惑うと思います。)

 

3眼式の実体顕微鏡の場合、カメラポートは左右どちらかの映像となります。
(映像も斜視となります。)

 

デメリットとしては、高倍率の観察ができません。
(製造時に左右の微妙な調整が必要な為です。)
倍率は比較的低倍率となります。ズーム比もそれ程大きくありません。
汎用的なもので、10~50倍程度、高倍率タイプでも100倍程度が実体顕微鏡の限界となります。

 

また、長時間の作業では作業者のストレスが大きくなります。
目幅調整、視度調整 等、観察者個人ごとの調整が必要です。

 

左右で視野が異なるので、正確な位置決め、2次元の寸法測定には不向きです。
上記の用途で顕微鏡を使う場合は、単眼顕微鏡を使います。

2. 倍率の違い

実体顕微鏡とマイクロスコープの倍率は単純に比較ができません。
実体顕微鏡は目で確認するのに対して、マイクロスコープはモニタで観察します。

その時にモニタ倍率を含んでしまいます。

 

倍率での単純比較はできませんが、観察視野で比較すると単純な比較ができます。

 

例えば、

THE DIFFERENCE BETWEEN AN ELECTRON MICROSCOPE AND A STEREOMICROSCOPE

Electron microscopes and stereomicroscopes each carry their own unique benefits and drawbacks. Understanding the specific characteristics of each type is important to use them flexibly.

 

In general, if expressed in English, both can be called “microscopes”. Although in industry there are instances when microscopes are referred to as microscopes, in this case we will explain “microscopes” in terms of single-eyehole digital display machines.

 1. Difference in Characteristics

・Features of Physical Optical Microscopy:

One big difference is that the Entity Optical Microscope is designed with two independent optical systems, creating two independent light paths on the right and left.

When observing with a physical Optical Microscope, the viewing range from right and left will be different. If you place a coin as follows to observe:

When observing, the observer will see both different visions as a single image, similar to how humans have two eyes.

 

The benefit of this is that the object will look like a real space. You can also understand the feeling of near and far, so people doing processing work often need to use Physical Optical Microscopy. The downside is that it requires a bit of technique when using (first-time users may feel strange about the unnatural image).

 

In the case of a Trinocular Optical Microscope, the camera port will contain an image from one side, either the right or left side (the image will also have a tilt effect).

 

Another disadvantage is the inability to observe at high magnification (due to the need for delicate adjustment between the right and left sides during manufacturing). The magnification is usually low and the magnification ratio is not large. Normally, even for general types, magnification is only 10 to 50 times, and in high-end cases, only about 100 times is the limit of physical Optical Microscopy.

 

Furthermore, in long-term work, workers can experience a lot of pressure. Eye widening, vision correction, and personal adjustments by the observer are necessary.

 

Because the field of vision is different between right and left, it is not suitable for precise positioning and two-dimensional measurement. In the above applications, people often use monocular microscopes.

・Features of Microscope:

Basically, it mainly uses single lens.

Just like when people look at objects with one eye, this has the disadvantage of making it difficult to perceive near and far. In the case of the coin mentioned above, when viewed from the center of the lens, the image will look like this:

Because it is possible to choose from a variety of lenses, the microscope can accommodate from low to high magnification (exceeding 2000x).

 

Furthermore, with on-screen observation, even new users can easily observe without causing fatigue, suitable for long-term observation (inspection).

Due to the frontal view (upward angle), it is also suitable for locating and measuring dimensions. It is compatible with computers and can use a variety of software such as image storage, image processing, focus fusion, and many other features.

 

2. Difference in Magnification

Magnification between Physical Optical Microscopy and Microscopy cannot be directly compared. While Optical Microscopy is visually confirmed, Microscopy is observed on a screen.

 

At that time, the magnification of the screen must be taken into account.

Although a direct comparison of magnification is not possible, if the comparison is based on the field of observation, a simple difference can be seen.

 

For example, the field of view of a microscope is calculated by the number of fields. For a microscope with 20 fields, when magnified to 10 times, the field of view will have a diameter of 20 mm.

If one wants to observe the same field as in the mentioned physical Optical Microscopy, with the Microscope below, the magnification will be 20 times.

 

(Meanwhile, in Organic Optical Microscopy, the magnification is only 10 times.)

Furthermore, in the case of a Microscope, the magnification will vary according to the screen size.

 

For details, see the article below.

 

3. Differences in Primary Applications

・Physical Optical Microscopy is suitable for applications such as:

Installation, machining, physical object inspection/observation, etc.

 

・The microscope is suitable for applications such as:
Check appearance, determine precise positioning (such as shaft placement), measure dimensions without surface deviation, etc.
