ZJSC-TDB03 Flashlight Laser Material Evidence Discovery Device

1. Product introduction:
The 445nm pure blue laser can irradiate human body fluids (common carriers: fingerprints, sweat, urine, blood, sperm spots, etc.), fibers, bone fragments, dandruff, nails, and other biological evidence when the power is large enough. , By irradiating the fluorescent substance in the physical evidence to excite the inherent fluorescence reaction to emit different wavelengths of fluorescence, and then filter the blue light emitted by the laser itself through the filter, the inherent fluorescence of the biological evidence itself is revealed, which can be directly Shooting and extraction can effectively observe and record the signal light and images emitted by fingerprints and other traces. Generally, the blue laser has a very good appearance in the search and discovery of biological evidence such as forensic DNA.

 
2. Product advantages:
1. Non-destructive inspection, which can directly obtain the most original and true information, and does not damage biologically active substances (DNA).
2. It can directly detect sweat fingerprints, dust fingerprints, occult blood fingerprints and oily fingerprints, which is far superior to other light sources.
3. It has a super discovery function for biologically active ingredients, such as semen spots, saliva spots, sweat spots, urine spots, hair, exfoliated cells, bone and tooth fragments, etc., stronger than conventional light sources.
4. Auxiliary function: Comes with a tripod fixing hole, which can be fixed on a tripod.
5. Power prompt function: Built-in low power prompt function, when the power is less than 20%, the metal button switch flashes red.
6. Stable performance: In the case of continuous use for more than 8 hours, it can still be used normally, and the core components will not be damaged.
