optical filters for multiband Forensic Light source:
Light source used for criminal detection in the past, is mainly UV light, lasers, blue lights etc. although these light sources have high strength, good color, but usually more bulky and lower energy conversion rate, limited output wavelength , poor to output high-intensity white light, it can not be good to meet the practical needs. In order to test the evidence and give full play the role of various optical testing methods, to adapt to the needs of the scientific development of criminal techniques, criminal domestic and international technology sector is developed to replace the multi-band light source mentioned above. Various optical test methods continue to be applied to criminal technology,
Multi-band light source devides white light into different bands by teams of special color filter, and through light pipe to light output, this optical system to be known as multi-band light. High-quality bandpass interference color filter, select the appropriate combination of light output needed.
At present large-scale multi-band light source can be equipped with a dozen filters. More complete performance, a wider band (6 - 25 band ,280 - 1100nm). Can effectively stimulate fluorescence, elimination of background interference, traces of contrast enhancement.
Applications: multi-band police light source, Document Retrieval, UV photographs .
