Abstract Share this page

Evaluation of the detection capabilities of both laser and ultraviolet light sources was performed. The Spectra-Physics Model 171-19 argon ion laser was used in a comparison with the hand held Mineralight® multiband ultraviolet lamp, Model UVSL-58 and the Fotodyne Foto UV 410. Model 3-4100. Both techniques were evaluated as to their detection limits for various biological stains. A serial dilution was made from semen, saliva, and sweat samples and their corresponding stains were examined under laser and ultraviolet light sources. The techniques were also evaluated as to possible interferences which may arise based on the type of fabric the stains were made on. The advantages and disadvantages of each technique in relationship to their initial costs are discussed.
