The GSB-4A intelligent photoelectric spectral comparison analyzer is a new type of criminal investigation and judicial identification instrument launched for the first time in China. It combines optical imaging technology for spectral analysis and computer image processing technology to achieve macroscopic and microscopic comparison of two or more objects, and distinguish their similarities and differences. The instrument uses various lighting methods and different wavelengths of light waves to magnify and display the potential image of the object being tested.

1. The inspected object is placed in the same objective field of view and magnified for imaging under the same illumination conditions, eliminating the differences in comparison results caused by differences in two optical systems and lighting conditions;

2. Computer storage technology, where two or more objects under inspection do not need to appear simultaneously;

3. Image processing software stores, real-time collects, and edits microscopic images to achieve comparison of two or more images. Compare the diverse changes in the field of view and cutting edge lines to achieve overlapping fields of view and multiple imaging methods docking;

4. Equipped with two sets of multi band light sources for reception and excitation. Can be used alone or in combination, with powerful document inspection function

5. Multi band spectral selection, worktable adjustment, and electric control of various light sources are simple and convenient.

6. The instrument is equipped with multiple accessories, which can be used for document inspection or trace inspection.

7. Video printing, clear images, fast and timely printing.

This product is an ideal instrument for judicial appraisal and teaching in public security, procuratorial, court and their colleges and universities (for identifying fingerprints, bullet marks, tool marks, seals, texts, etc.). It is also suitable for banks, taxation, customs, cultural relics and other departments to identify printed materials such as coins, tickets, protective photos, cultural relics, etc.
