~Primary usage:
1. Laser: Detect the fluorescence reactions of material evidence, such as fingerprints (on metal surface, plastic mats, duplicating paper and label paper), saliva, semen stains, traces of blood, urine traces, sweat stains, fiber, broken bones, 79% heroin, 42% methamphetamine and shooting residues on textiles, etc. Information searching of hidden material evidence.
2.LED light source: detect or take photographs: fingerprints and traces on the objects which are highly reflective or transparent. Search the material evidence which cannot be detected by laser due to its characteristics: such as fingerprints, dust traces and other material evidence that cannot be detected or photographed by laser light.
Main parameters
Power supply: 220V or 24V battery pack.
Battery: external lithium iron phosphate battery pack, capacity: 12Ah, charging voltage: 29.2V.
Wavelength:
Laser: 530nm , 445nm
LED light source: white light: 6,000K-7,000K, Green light: 520nm, Blue light: 470nm
Laser output mode: multimode optical fiber, length of optical fiber: ≥2.5 m
Output mode of LED light source: uniform light lens group
Laser spot size: light spot diameter at 0.5 m: ≥7cm
Light spot size of LED light source: light spot diameter at 0.5 m:≥φ22mm
Light spot features: uniform light output, uniformity of light spots ≥95%
Structure features: all-in-one, shock and moisture proof housing. Single machine five-band output.
Operation:
1. On the handle there are switching buttons for LED light source and laser light source.
2. LED light source switching button: white light- 520nm- 470nm in sequential cycle.
3. Laser light source switching button: 532nm- 445nm- neutral. Cycle by sequence
4. When the instrument is in laser light source mode, the starting light will always be the weakest light no matter selecting which wavelength (in case the user does not wear protective glasses or wear wrong ones)。There is a button in the handle for adjusting output power. The laser output power can be adjusted steplessly.
The handle can be held in hand or fixed to a tripod through the tripod interface on it, making it convenient for taking photographs.
After switching the laser intensity, the laser light will always grow from the weak intensity to strong intensity, so as to protect the eyes of the operator.
Protective glasses: two pairs for each 190-540nm and 190-470nm
