Crime-lite ASV Applications

 

A SAFE VIEWING ENCLOSURE FOR THE VISUALISATION OF ANTI-STOKES FINGERPRINT POWDERS

 

Latent fingerprints, invisible under white light, appear to glow brightly in the visible spectrum when dusted with anti-Stokes (up-convertor) powder and illuminated under an intense infrared light.

Visualisation of fingerprints using anti-Stokes powders is of particular use in situations where background fluorescence overwhelms the fluorescence produced using alternative fingerprint dyes/stains, on exhibits that cannot be 'dipped' into wet treatments such as BY-40, and on metal exhibits (this is due to the magnetic properties of anti-Stokes powders).

 

Typical exhibits that benefit from ASV development include:

  • Paper and card including banknotes, passports, magazines etc.
  • Smooth metal surfaces including drinks cans
  • Electronics such as mobile phones
  • Firearms, that require test firing following treatment
