What Light Shows Fingerprints. Some surfaces create more of a challenge when detecting fingerprints, such as a highly contrasting printed page or porous. It has been reported that 280 nm is the optimal excitation. In this chapter, visual examination of fingerprints under various lightings (visible, uv, ir) is discussed. The who, what, where, and when of wavelengths. When illuminated with uv light, fingerprints emit at 330 and a 440 nm, the emission at 330 nm being the strongest. Forensic light sources enhance the detection of latent fingerprints by complementing traditional light sources with fluorescent. After 30 seconds, investigators can use a uv light to see invisible fingerprints “glow”. This strong luminescent effect creates a greater contrast between the latent print and. (courtesy of scott campbell, ron smith &. The first phase involves looking for patent and. Using a fluorescent dye stain and an orange alternate light source helps this latent print appear clearly so that it can be documented.
