Fingerprints are one of the most valuable forms of evidence linking a criminal to a crime scene.  Most often, the fingerprints are not visible and must be detected by adequate physical and chemical techniques.  Traditional methods like the use of powders or Ninhydrine reagent often lack sensitivity or they produce weak contrasted images.  Modern fingerprint examination methods focus on enhanced procedures to improve detection and enhance contrast.

Fingerprints

The ability to detect fingerprints by fluorescence is dependent upon several factors.  These include: illumination wavelength (appropriate to the chemicals involved) viewing wavelength and the illumination intensity.  These demands are met by the use of alternative light sources which provides high illumination intensity at different wavelengths to produce sufficient fluorescence within a defined spectrum band.

Especially designed for the detection and recording of latent fingerprints, this alternative lighting set includes the cold light source with liquid light guide and focusing lens.  The filter slot in the light source is equipped with a blank filter holder for your own customized excitation filter.  The light source will also provide non-filtered white light and is most versatile of any forensic work.
