INFRARED FLUORESCENT FINGERPRINT POWDERS

 

fpNatural IR Fluorescent Fingerprint Powders enable examiners to reveal high contrast finger marks whilst suppressing background interference.

Both powders emit bright fluorescence in the infrared region of the spectrum; fpNatural 1 powder is excited by red or blue illumination, fpNatural 2 powder is excited by near-infrared illumination.

Visualisation of both powders is achieved using an IR sensitive camera equipped with an IR pass filter to block out all other wavelengths.
