TECHNOLOGY FOR FORENSIC LIGHT SOURCE EXAMINATION

 

DETECT & EXAMINE: Body Fluids

 

The detection of body fluids including semen, sweat, saliva, urine and vaginal secretion can be vital to criminal investigations. Multi-wavelength illumination provides a quick and contactless way to detect suspect traces of body fluids.

 

Visualisation Wavelengths: 

UV light is widely used to exploit the natural fluorescent properties in body fluids

Violet and Blue illumination can be used to excite fluorescence in body fluids and is particularly useful when searching on a substrate the fluoresces under UV.
