As we mentioned above, florescence

As we mentioned above, florescence examination of fingerprints with visible
light sources is carried out by almost all forensic laboratories. Examination
with visible light needs chemical developments, such as application of
cyanoacrylate and chemical dyes, which means laboratory conditions and
consumption of time. It is not possible to carry out this type of florescence examination
at the crime scene. For this reason, the crime scene examiner
should perform it in the laboratory.
