An australian scientist has developed a new crime scene identification technique for fingerprint detection and analysis that works by adding a drop of liquid that contains crystals to surfaces.
Ultraviolet uv light technologies are used for multiple purposes in forensic investigations including authenticating paintings and other fine art authenticating signatures analyzing questioned documents illuminating latent fingerprints at crime scenes and trace evidence on clothing analyzing ink stains and revealing residual stains of body fluids.
This system features the new arrowhead 16mp digital ruvis camera with sensitivity from the deep uv through the visible and into the near ir spectrum.
This light is available in four wavelengths.
