forensic science

Forensic lamps are high energy light sources that emit all the three types of lights - ultraviolet light, visible light, and infrared light.

Option D.

Forensic lamps are important tools in the forensic investigations at any crime scenes. It helps the investigators to detect any sort of fingerprints, body fluids, hair and fibers, bruises, bite marks, wound patterns, shoe and foot imprints, gun shot residues, semen marks, drug traces, questioned documents, bone fragment detection, etc. Most importantly, it helps in the detection of latent finger prints that are important evidence in any crime scenes.

The forensic lamps are made up of powerful light sources that can divide the light according to different groups of wavelengths that help in the easy visualization of the evidence. The three types of visualization includes fluorescence ( as in semen mark), absorption (as in blood serum mark) or oblique lighting( gun shot residues).
