The light sources of different wavelengths are used in the field of criminalistics for locating items of forensic interest during inspection of a scene from the fact. This is a very effective method that does not alter the test samples, allowing suspect the presence of biological materials such as body fluids (sangre, semen, urine, etc.), pelos, bones and teeth; and non-biological, as gunshot residue and synthetic fibers, among other potential physical evidence.
Alternative light sources may also be applied in other forensic fields, as in documentología, allowing identification document security measures and maneuvers adulterativas.
