TECHNOLOGY FOR THE DETECTION, CAPTURE & ENHANCEMENT OF FINGERPRINTS

 

Anti-Stokes

 

Anti-Stokes fingerprint dusting powders, also known as up-convertors, are a relatively new technology for the enhancement of latent fingerprints and are particularly useful when attempting to visualise fingerprints against 'busy' multi-coloured backgrounds.

Manufactured using rare-earth metals, anti-Stokes powders absorb invisible infrared radiation and re-emit the energy at visible wavelengths in a process that is the reverse of standard (Stokes) fluorescence.
