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.


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.

The NSH500CSU comes standard with a simple XY panel but does not support transmitted lighting, so we will cover how to install a transmitted lighting system.


◆Method 1
How to attach the rubber feet to the RD-95T and place it on the standard XY platform (TK100)



Light can be easily passed through without processing, but the size of the object is limited to the size (φ95) that can be placed on the RD-95T.

Because it has rubber feet, it will not slip, but the lamp body may move due to impacts such as being hit by your hand.


◆Method 2
How to switch to the XY turntable simply, remove the observation plate and install the RD-95T




Since the RD-95T can be mounted to the XY table, it can be fixed to some extent.
Since it is necessary to route the cable to the outside, it is necessary to drill a hole about φ10 in size in the base.
We can also drill holes for free before shipping.

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.


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.)


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.


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)

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.





In this scenario, the utilization of our LED Angle (LED-A2) enables polarized observations.







LEDs are affixed beneath the angle.

(Caution) The installation space for the angle cannot be secured unless the focal length is elongated. Consequently, it can only be utilized when employing auxiliary lenses to reduce magnification.

Which camera between a USB camera and a GigE camera offers superior usability?


Comparison of USB Cameras and GigE Cameras

  USB Camera GigE camera
Price No significant price difference No significant price difference
PC Connection Port USB Port LAN Port
Connection Cable USB Cable Universal Ethernet Cable (LAN Cable)
Cable Extension Up to 3m (※1) Up to 100m
Communication Stability △ (Moderate) ◎ (Excellent)
Camera Power Supply Supplied from the computer External power supply required
Initial Setup (Environmental Configuration) Simple Slightly Complex


*Note 1: According to the USB standard, the maximum recommended cable length is 3m. Beyond this distance, there are USB cables available with repeater functions, such as 5m or 10m options. However, in such cases, communication stability may experience a substantial decline, and there is a notable occurrence of display issues, including instances where the image may not appear.



I would like to consider which camera is more user-friendly


The USB camera, as the name suggests, is a camera designed for use with a computer via a USB connection. It utilizes a USB cable to connect to the computer’s USB port. In the case of USB cameras, both data communication to the computer and power supply to the camera can be accomplished with a single USB cable.


On the other hand, GigE camera stands for Gigabit Ethernet camera. It uses a general-purpose Ethernet cable (LAN cable) to connect to the computer’s LAN port. Unlike USB cameras, standard LAN ports on computers usually do not have power supply lines. Therefore, additional power supply from a PLC to the camera or a separate power source for camera operation is required for GigE cameras. If simplicity of setup is a priority, then the USB camera is recommended.



Let’s now consider distance and communication stability


USB cables for USB cameras are typically limited to a length of 3 meters according to the standard specification. There are USB cables available with repeater (signal amplification) functionality, extending up to 5 or 10 meters, but their communication stability significantly deteriorates compared to the 3-meter length.


In contrast, GigE cameras can operate up to 100 meters. When comparing GigE cameras and USB cameras at the same distance, GigE cameras exhibit superior communication stability. Therefore, particularly for long-distance connections, constructing with a GigE camera is recommended. With a setup involving GigE cameras, communication stability is outstanding.





Both USB and GigE cameras have their merits and demerits. It’s best to select based on your specific needs. At our company, we offer demonstration models for both USB and GigE cameras. Why not give them a try? We’re also here to assist with selecting the right industrial camera. Feel free to contact us for any inquiries.

Microscope Selection Guide

Microscope Selection Guide

<STEP 1> Start by choosing the type of camera


  USB Type 4K Type High-Definition Type

Some models come with built-in measurement, line generation, and drawing functions, eliminating the need for a computer; it can be directly connected to the monitor, making it optimal for inspections.。
Demerit The display speed is proportionally affected by the resolution due to its dependency on USB communication speed. It can only be used with monitors that have an HDMI port and support 4K resolution. It can only be used with monitors that have an HDMI port and support Full HD resolution.
  It is convenient when there is a need for image processing such as measurement, focus stacking, and binarization. It is also useful when capturing images for reports and submissions. If visual inspection is the primary use and a clearer, higher-quality image is desired for observation. If visual inspection is the primary use and you want to observe with even clearer (high-quality) images.




<STEP 2> Consider the magnification.

Microscope magnification is relative; unlike microscopes, there’s no absolute magnification. It also changes depending on the monitor’s size. On our Matsuden website, we list values based on using a 17-inch monitor. We also provide the field of view. The field of view remains constant regardless of monitor size, serving as a reference when selecting microscopes.



1. Method to Determine the Magnification of a Microscope 




You can actually measure it on the monitor you’re using. The magnification of a microscope is determined by how much the actual object appears magnified on the monitor. For instance, if a 1mm object appears as 10mm on the screen, it would be considered a total magnification of 10x.











2. Method to Calculate the Magnification of a Microscope 




Certainly! The formula for calculating the monitor’s magnification is:

Monitor Magnification = Monitor Size in inches x 25.4 (1 inch) ÷ Camera Sensor Size (diagonal)

The table below displays the calculated monitor magnification for various camera sizes. (For a 17-inch monitor)





Camera inch 1/2inch 1/2.5inch 1/3 inch
monitor magnification 54 62 72

Certainly! The formula to calculate the total magnification is as follows:

\[ \text{Total Magnification} = \text{Monitor Magnification} \times (\text{Lens Magnification} \times \text{Eyepiece Magnification}) \]

For example, if you have a 1/2-inch CCD camera (diagonal 8mm) combined with the settings of the right lens, the magnification on a 17-inch monitor would be calculated as follows:

\[ \text{Monitor Magnification} = \frac{17 \times 25.4}{8} = 54 \]

\[ \text{Total Magnification} = 54 \times (2.5 \times 0.5) = 67.5 \]

Note: If you are using a x1 (1x) eyepiece, it may not be explicitly mentioned in the lens specifications.






<STEP3> Choosing the lighting.




Ring illumination is widely acclaimed for its versatility, serving as the predominant lighting modality in numerous microscope configurations. 白色LEDリング照明



Now, what might constitute entities that prove challenging for effective observation under the aegis of ring illumination?





Highly polished metals, plated metals, and mirror-like surfaces such as silicon wafers are best observed using coaxial illumination microscopy.





Objects characterized by a mixture of high and low reflectivity, such as solder on substrates or the surface of vinyl, pose challenges for observation. →Halation removal is best addressed through the utilization of a microscope.

Microscope Overview

Microscopes and Optical Microscopes: Understanding the Differences


Microscopes and optical microscopes each have their own advantages and disadvantages. It is crucial to comprehend their distinctive features to use them appropriately. Technically, even optical microscopes can be referred to as microscopes when expressed in English. In certain industries, the term “microscope” is used interchangeably with “optical microscope.” However, for the purpose of this discussion, we will focus on explaining monocular digital microscopes as microscopes.




Distinguishing Magnification in Microscopes and Optical Microscopes


The concept of magnification differs between microscopes and optical microscopes, making them distinct in terms of magnification principles.

For optical microscopes, if the magnification is the same, regardless of the manufacturer, it results in the same field of view. This is termed absolute magnification (although the field of view may vary strictly based on the eyepiece lens’s field number). On the other hand, in the case of microscopes, even with the same magnification, the field of view can differ between manufacturers. This is referred to as relative magnification.




Applications and Capabilities of Microscopes


A microscope, whether it be a USB type, 4K type, or high-definition type equipped with an industrial camera, is a tool designed for magnifying and observing objects. It allows for the enlargement and observation of subjects, coupled with the capability to assess and analyze the observed images.

Unlike direct peering into a microscope, the real-time projection of the observed specimen onto a monitor screen enables simultaneous viewing by multiple individuals, facilitating collaborative observation and analysis.

About 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 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  




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.


Check if a USB port is USB 3.0 on or not


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

【Method 1】Check the port color:
USB 3.0 ports are typically recommended to be colored blue, and in most cases, they are indeed blue.







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.





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)





※ 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.







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.




– 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.
