Product Description

Introduction

BS-4020 industrial inspection microscope has been specially designed for inspections of various size wafers and large PCB. This microscope can provide a reliable, comfortable and precise observation experience. With perfectly performed structure, high-definition optical system and ergonomical operating system, BS-4020 realizes professional analysis and meets various needs of research and inspection of wafers, FPD, circuit package, PCB, material science, precision casting, metalloceramics, precision mould, semiconductor and electronics etc.

Features

1. Perfect microscopic illumination system.

The microscope comes with Kohler illumination, provides bright and uniform illumination throughout the viewing field. Coordinated with infinity optical system NIS45, high NA and LWD objective, perfect microscopic imaging can be provided.
 

2. High quality Semi-APO and APO Bright field &Dark field objectives.

By adopting multilayer coating technology, NIS45 series Semi-APO and APO objective lens can compensate spherical aberration and the chromatic aberration from ultraviolet to near infrared. The sharpness, resolution and color rendition of the images can be guaranteed. The image with high-resolution and flat image for various magnifications can be got.
 

3. The operating panel is in the front of the microscope, convenient to operate.
The mechanism control panel is located in the front of the microscope (near the operator), which makes the operation more quickly and conveniently when observing the sample. And it can reduce the fatigue caused by long time observation and the floating dust brought by a big range of movement.
4. Ergo tilting trinocular viewing head.

The Ergo tilting viewing head can make the observation more comfortable, so as to minimize the muscle tension and discomfort caused by long hours of working.
 

5. Focusing mechanism and fine adjustment handle of stage with low hand position.

The focusing mechanism and fine adjustment handle of stage adopt the low hand position design, which conforms to the ergonomic design. Users no need to raise hands when operating, which gives the greatest degree of comfortable feeling.
 

6. The stage has a built-in clutching handle.
The clutching handle can realize the fast and slow movement mode of the stage and can quickly locate large-area samples. It will no longer be difficult to locate the samples quickly and accurately when co-using with the fine adjustment handle of stage.
7. Oversized stage (14"x 12") can be used for large wafers and PCB.
The areas of microelectronics and semiconductor samples, especially wafer, tend to be large, so ordinary metallographic microscope stage cannot meet their observation needs. BS-4020 has an oversized stage with a large movement range, and it is convenient and easy to move. So it is an ideal instrument for microscopic observation of large area industrial samples.
8. 12" wafers holder comes with the microscope.

12" wafer and smaller size wafer can be observed with this microscope, with fast and fine movement stage handle, it can greatly improve the working efficiency.
 

9. Anti-static protective cover can reduce dust.

Industrial samples should be far away from floating dust, and a bit of dust can affect product quality and test results.
BS-4020 has a large area of anti-static protective cover, which can prevent from the floating dust and fall dust so as to protect the samples and make the test result more accurate.
 

10. Longer working distance and high NA objective.
 

The electronic components and semiconductors on circuit board samples have difference in height. Therefore, long working distance objectives have been adopted on this microscope. Meanwhile, in order to satisfy the industrial samples' high requirements on color reproduction, the multilayer coating technology has been developed and improved over the years and BF&DF semi-APO and APO objective with high NA are adopted, which can restore the real color of samples.
 

11. Various observation methods can meet diverse testing requirements.
