Forensic Alternative LED Light Source(up to 13wavelengths) OR-GSS300 Main characteristics: It is hand-held operated and its wavelengths and irradiation angle can be adjusted by one hand. Uniform and purity light output, single lens outputs light spot. No need to adjust light spot. Instant startup and wavelengths switching. Integrated design of battery, light source and lens. Easy to carry and use. It is equipped with a tripod interface, through which the instrument can be fixed to the tripod for taking photographs. Integrated design of white strong light and multi-band light source. It can rapidly find out various suspicious material evidence, trace, fingerprints, body fluids and semen stains, etc. in crime scene or laboratory. Color separation photography can be performed. Treat the material evidence or its fluorescence with the excitation reagent of a particular wavelength.
