Sirchie Silver/Redescent Fluorescent Latent Print Powder, 2oz/59ml

The Sirchie Silver/Redescent Fluorescent Print Powder (2oz/59ml) works especially well on dark or multicolored surfaces-greatly enhancing ridge details when illuminated with an ultraviolet light. Typically, light in the ultraviolet or blue parts of the spectrum (254nm to 525nm) is used to excite the fluorescence.
