Tips for Observing Glossy Convex Surfaces

Glossy convex surfaces can be challenging to observe with the standard ring illumination equipped on our microscopes, as reflections may occur.

■ Illumination

 

Using the standard ring illumination can significantly amplify the impact of reflections. Attaching a polarizing filter to the tip of the lens and the illumination side during ring illumination usage can provide some improvement.
照明による見え方の違い
   
Using twin-arm illumination, as shown in the photo below, allows for further reduction of reflections. (Adjustments to the angle may be necessary.) Simply inserting a polarizing filter into the lens alone can lead to further improvement, as shown in the photo below.
ツインアーム照明使用時
   
Observation using the same method (ring illumination → low-angle twin-arm illumination) for a convex lens (subject).

(Note) In the case of lenses, since the lens itself is transparent, the background color also becomes crucial. The above example features a white background, and the lens is observed with a raised position rather than being placed directly on the surface.

 

Types and characteristics of telecentric lenses.

Key Features of Telecentric Lenses:

1. No expansion or contraction of images within the depth of field.
→ Enables reduced measurement errors in dimensional measurements.
2. Minimal image distortion due to parallax.
3. When used with coaxial illumination, less unevenness in the brightness of the target object.

There are two main types: bilateral telecentric lenses and unilateral telecentric lenses.
Our company handles both bilateral and unilateral telecentric lenses.

The respective characteristics are as follows:

 

両側テレセンリックレンズ

 

Bilateral Telecentric Lenses

Bilateral telecentric lenses possess a feature where the size of the projected object remains unchanged regardless of alterations in the distance on either the camera sensor or subject side. In other words, by adjusting the distance solely between the lens and the subject, using, for instance, macro extension rings to modify the distance on the camera sensor side, one can alter the distance without changing the magnification. However, as the physical diameter of the lens increases compared to the projected area, larger lens sizes are required for lower magnifications, resulting in higher prices. These lenses are commonly employed in precision measurement devices and projectors.

Unilateral Telecentric Lens

 

片側テレセントリックレンズ

 

Unilateral Telecentric Lens

This lens has a telecentric lens structure only on the subject side. Unlike bilateral telecentric lenses, changes in the distance on the camera sensor side will alter the size of the projected subject similarly to non-telecentric lenses. Compared to bilateral telecentric lenses, unilateral lenses are smaller in size and more cost-effective. They are sometimes adopted as a replacement for fixed magnification in dimensional measurement applications where macro zoom lenses are unnecessary.

(In addition to the subject-side telecentric lenses we offer, there are also lens-side telecentric lenses where only the camera sensor side features a telecentric lens structure. These are seldom used for work photography with conventional cameras.)

A distance of 170 mm can be secured from the lens tip to the target object.

For this level of magnification, there is not a significant difference in resolution compared to our company’s zoom lenses.

However, it is effective if there is a strong preference for minimizing the size of the lens and camera.

Regarding the ports of the computer for connecting a USB 3.0 camera.

USB 3.0 cameras that comply with the USB 3.0 standard exhibit high power delivery capabilities and communication speeds.

However, it is important to connect them to the correct ports on the computer to ensure proper functionality.

In this instance, I will provide information on the appropriate ports on the computer for connecting a USB 3.0 camera.

 

The USB port to be used when connecting a USB 3.0 camera.

 

 

To utilize a USB 3.0 camera, it is essential to connect it to a USB port on your computer that supports USB 3.0 (or USB 3.1, USB 3.2) specifications.

If a USB 3.0 camera is connected to a USB 2.0 port, it will not function properly due to limitations in power delivery and communication speed.

 

■ Differences between USB 1.1, 2.0, and 3.0

 

Specification Maximum Data Transfer Speed

Power Delivery Capability

 
USB 1.1 12 Mbps 5V 100mA

USB 2.0

 

 480 Mbps

5V 500mA

 

USB 3.2 Gen1 (USB 3.0)

 

 5 Gbps 5V 900mA
USB 3.2 Gen2 10 Gbps 5V 900mA
USB 3.2 Gen2x2 20 Gbps

5V 900mA

 

 

※ USB 3.0 was renamed to USB 3.1 Gen1 in 2013, and then to USB 3.2 Gen1 in 2019.

As mentioned above, in terms of numbers, the maximum data transfer speed (communication speed) of USB 2.0 is 40 times faster than USB 1.1, while USB 3.0 is approximately 400 times faster than USB 1.1.

 

 

There are three methods to verify if a USB port on your computer is USB 3.0:

 

【Method 1】Check the port color:

 

USB 3.0 ports are often designated with a distinct blue color.

 

USB3.0ポートの確認1

 

 

However, occasionally USB 3.0 ports may not be blue, and conversely, not all blue ports are necessarily USB 3.0.

In such cases, please refer to 【Method 2】 and 【Method 3】.

 

【Method 2】Check for symbol markings:

If you find a symbol marking near the USB port that includes “SS” (SuperSpeed), it indicates that the port is USB 3.0.

 

 

 

USB3.0ポートの確認2

 

 

However, there are cases where there may be no symbol markings.

If there are no markings, please refer to 【Method 3】.

 

【Method 3】Verify through Device Manager:

 

You can check the USB port specification by accessing the Device Manager on your computer.

(Device Manager > Universal Serial Bus controllers)

 

 

USB3.0ポートの確認3

 

※ The image shown is for Windows 10. Additionally, the types and number of ports may vary depending on your computer. 

 

When connecting a USB 3.0 camera to your computer, please be mindful of the following considerations:

As of 2023, the majority of commercially available computers are equipped with USB 3.0 ports.

However, some computers with multiple ports may have both “USB 3.0” and “USB 2.0” ports available. 

 

 

 

USB3.0ポートの確認4

 

 

Please note the following when connecting a USB 3.0 camera to your computer:

Ensure that you verify the USB ports on your computer before connecting the camera.
Connect the camera directly to the computer without the use of intermediaries such as USB hubs.
It is worth mentioning that certain hubs may result in insufficient power or compromised communication speed, potentially leading to operational irregularities.

 

 

Summary:

 

A USB 3.0 camera is a camera that supports the USB 3.0 standard, offering higher power delivery capabilities and faster communication speeds.
To ensure proper functionality, be sure to connect the USB 3.0 camera to a USB 3.0 (or USB 3.1, USB 3.2) port.
