Mini high power police laser

532nm laser is a newest police quipment in crime ivestigation field. High power(higher than 5 watts) 532nm laser excites many kinds of weak, potential or invisible crime evidences to give out fluorescence, for instance, fingerprint footprint, blood, secration, hair, fiber, gunpowder vestige and others, the fluorescence image of crime evidences can be recorded by a camera for forensic use. Especiallly, the police laser resolves tradional crime investigation difficult problems: Firstly, it acquires evdence’s images on irreflexcive surface such as wall, coarse paper, leather, skin surface and others. Secondly, it acquires timeworn evdence’s images, in some cases, fingerprints even exceed 40 years were found and recorded by using police laser. The biggest problem of traditional police laser is big size and heavy for technical reasons, at present , normal police laser is too heavy to be carried by single person, some advanced police laser is bigger than 40x30x35mm3, heavier than 20 kilograms, can hardly be used in a crime site. But most evidences are located in a crime site and unable to move. As a result, normal police laser usually lies in a laboratory, andseldom be used in real cases. Built with newest advanced laser technology, Zhi Hai police laser is a smallest high power laser so far, at the same time is a high power laser up to 8 watt, the laser is so small that could be carried and operated by single person easily. Features: Small size. The volume is about 160x110x80mm3, weight is lower than 6 kilograms. High power. Output laser power adjustable form 0-8 watts. Portable. The laser is assembled with a lithium battery. For first time, the police laser can be hold and operated by a single person in a crime site. Parameters: Light spot diameter: in a distance of 60cm, diameter is 15-30mm adjustable. Wave length: 532 nm, width 0.5mm.
