Understanding Yizhan Industrial Stereo Microscopes and Digital Monocular Microscope Systems

When choosing an industrial microscope for electronics repair, PCB inspection, soldering, quality control, or precision assembly, understanding the microscope system and its components is essential.

At Yizhan, our microscope solutions are primarily divided into three categories:

• Stereo Microscopes

• Monocular Digital Microscope Systems

• Microscope Accessories

This guide explains how these systems work, how magnification is calculated, and how different accessories can help you achieve the ideal viewing experience for your application.

Yizhan Stereo Microscopes

Stereo microscopes are widely used in electronics manufacturing, PCB repair, jewelry inspection, precision assembly, and laboratory observation.

Unlike traditional biological microscopes, stereo microscopes provide a three-dimensional image with a long working distance, allowing users to operate tools underneath the microscope while viewing the object.

Stereo Microscope Configurations

Yizhan offers several stereo microscope configurations:

• Binocular Stereo Microscopes

• Trinocular Stereo Microscopes

• Various Stand Options

• Eyepiece Accessories

• Auxiliary Objective Lenses

How Magnification Works

The total magnification of a stereo microscope is determined by:

Total Magnification = Zoom Body Magnification × Eyepiece Magnification × Auxiliary Objective Magnification

Standard Configuration

Most Yizhan stereo microscopes come standard with:

• 10X Eyepieces

• 0.7X–4.5X Zoom Body

This combination provides a magnification range of:

7X–45X

This range is ideal for:

• PCB inspection

• Soldering work

• Mobile phone repair

• Component assembly

Increasing or Decreasing Magnification

Users can easily customize magnification by changing eyepieces or auxiliary objectives.

Example 1: 20X Eyepieces

Using 20X eyepieces:

0.7X × 20 = 14X

4.5X × 20 = 90X

Result:

14X–90X Magnification

Ideal for observing smaller electronic components.

Example 2: 0.5X Auxiliary Objective

Using a 0.5X auxiliary objective:

7X–45X × 0.5

Result:

3.5X–22.5X Magnification

Benefits:

• Larger field of view

• Longer working distance

• More room for soldering tools

Example 3: 2X Auxiliary Objective

Using a 2X auxiliary objective:

7X–45X × 2

Result:

14X–90X Magnification

Benefits:

• Higher detail observation

• Suitable for micro soldering and fine inspection

Understanding Working Distance

Working distance refers to the space between the microscope lens and the object being observed.

Using lower-power auxiliary objectives such as 0.5X can significantly increase working distance.

This is especially useful for:

• Soldering stations

• Rework operations

• Industrial assembly lines

Yizhan Monocular Digital Microscope Systems

For customers who prefer viewing images directly on a screen, Yizhan offers complete monocular digital microscope systems.

Unlike stereo microscopes, these systems are built around a digital imaging solution.

Components of a Monocular Microscope System

A typical Yizhan monocular microscope kit consists of:

1. Microscope Lens

The microscope lens determines the magnification and image quality of the system. Yizhan offers multiple lens options, including 130X, 150X, 180X, and 215X, allowing users to choose the most suitable magnification for PCB inspection, soldering, electronics repair, and precision assembly applications.

2. Adjustable Stand

The stand provides stability and flexible positioning for different inspection tasks. Yizhan offers various stand options, including folding arm stands, large bases, small bases, center-post stands, and universal articulating stands, allowing users to adjust the viewing angle, height, and working area for maximum convenience and efficiency.

3. CCD Camera

The CCD camera converts optical images into digital signals and displays them on a monitor or computer for real-time viewing, image capture, and video recording. Yizhan offers a range of CCD camera models, including XHU4002, XHU4003, XHU4005, XHU4006, XHU4011, XHU4012, XHU6001, VX1004, and XVH2002. All models support standard C-Mount and CS-Mount interfaces, ensuring compatibility with a wide variety of microscope lenses and optical systems.

4. LED Ring Light

The LED ring light provides uniform illumination for inspection work.

Together, these components create a powerful digital inspection system.

Changing Magnification with Different Objectives

Similar to stereo microscopes, monocular systems can achieve different magnification levels by changing objective lenses.

For example:

0.5X Objective

• Larger field of view

• Increased working distance

• Better for larger circuit boards

1X Objective

• Standard magnification

• General inspection tasks

2X Objective

• Higher magnification

• Fine solder joint inspection

• Microelectronics analysis

Users can select the objective lens that best fits their workflow.

USB CCD Cameras and Computer Connectivity

Many Yizhan CCD cameras feature USB connectivity.

With a USB camera, users can connect the microscope directly to a computer.

Benefits include:

• Real-time image display

• Image capture

• Video recording

• Measurement functions

• Quality documentation

• Training and presentations

Software control makes inspection work more efficient and allows teams to share images instantly.

Choosing the Right Yizhan Microscope

Choose a Stereo Microscope If You Need:

• Direct optical viewing

• Comfortable long-term observation

• PCB repair

• Soldering operations

• Precision assembly

Choose a Digital Monocular Microscope If You Need:

• Screen-based viewing

• Image capture

• Video recording

• Measurement and documentation

• Remote collaboration

Conclusion

Yizhan industrial microscope systems are designed to provide flexible magnification, excellent image quality, and practical solutions for electronics inspection and repair.

Whether you choose a stereo microscope with interchangeable eyepieces and auxiliary objectives or a digital monocular system with a USB CCD camera, Yizhan offers scalable solutions that can be customized to match your specific inspection requirements.
