- Ideal for photographing evidence or for photography of fluorescing body fluid stains
Fluorescent L-Shaped Scales, Pack of 5 Designed for use with a Forensic Light Source or ultraviolet lamp, this fluorescent L-shaped scale is ideal for photographing evidence such as latent prints developed with fluorescent dyes or powders, or for photography of fluorescing body fluid stains at crime scenes or on evidence. Inch markings are printed with fluorescent ink on a heavy, matte cardstock. Alternating bars every inch help to identify measurements in grossly over- or underexposed photographs. The L-shape of the scale and the crosshairs at each end provide lines of reference for the measurements and ensure the scale is parallel with the film plane.
