Forensic Light Sources For Detection Of Biological Evidences

Forensic alternate light sources als have been used for detection of biological evidences which can be detected due to their nature characteristic such as light asorption blood or flurescence effect semen saliva urine vaginal fluids sweat etc.

Forensic light sources for detection of biological evidences.

The black material absorbs all wavelengths of light including the excitation light from the light source and the emission fluorescence. Forensic light source techniques have been successfully utilized for revealing latent prints on these and many other types of textured surfaces backgrounds which mask ridge detail fragile surfaces and contaminated surfaces. Although some forensic investigators would occasionally use ultraviolet uv black light to examine for crime scene evidence white light was the mainstay.
