Forensic Glasses

Forensic glasses, when used in combination with a UV lamp, enable the investigator to more readily see traces of fluorescence at great distances. We sell yellow lens glasses, red lens glasses, and orange lens glasses for forensic examinations.

Knowing which glasses to use:
Knowing which forensic glasses in not an exact science.  Light conditions, the type of suface or material in question and state of the substance (wet, dry, new, old, etc…) often influence which filter/glasses combination works best.

Fluorescence and wavelengths:
Different substances react and fluoresce at different wavelengths.  While some substances may fluoresce when exposed to light of a certain wavelength, other substances might not fluoresce or be visible at all.

How Forensic glasses work:
Glasses filter away the undesired reflected light from the surface that is illuminated.  By using yellow filter glasses fitted with forensic filters, the investigator is able to significantly increase the possibilities of finding the exact evidence or traces that they are looking for, and filtering away unwanted traces.
