Summary: Hand-held portable multi-band light source for criminal investigation police uses 75W HID xenon lamp to output thirteen bands of monochrome light. It can excite the fluorescence of traces or background, enhance the contrast of traces, enhance the contrast of traces by the difference of absorptivity between traces and background, and take color separation photographs.
Product characteristics:
Output band: 13 bands can be output.
Product advantages:
1. Power supply by power adapter
Connect one end of the power adapter to the AC220V power supply and the other part to the main light source. Turn on the main switch and light up the light source. Selecting the dial wheel in the rotating band can select the desired band.
2. Excited fluorescence
CSS, 365, 415, 450, 490, 505, 530 and 555 nm can excite visible fluorescence of physical evidence. The visible fluorescence emitted by material evidence can be observed by illuminating the evidence with these light and wearing filter glasses matching the illuminated light.
In these bands, CSS has the strongest light intensity and the strongest ability to stimulate fluorescence. Wearing orange glasses and searching the scene with CSS light can often find some fluorescent evidence. White light and CSS light are very effective light sources for on-site search.
3. Color separation lighting
By changing the output band one by one, irradiating the material evidence and observing the contrast change between the material evidence and the background, we can find the biggest contrast between the material evidence and the background.
4. Battery Charging
When the battery can't drive the light source, it shows that the battery's power is running out, so it should be charged immediately. Connecting one end of the charger to the AC 220V power supply and the other end to the mainframe of the power supply, the battery can be charged and filled up for about 12 hours.
Batteries also slowly consume electricity when they are not in use. If the battery is completely exhausted, the battery will be scrapped. If the battery is not used for a long time, it should be charged every six months to prevent the battery from being scrapped.
