Sirchie REDescent 16oz Fluorescent Latent Print Powder

The Sirchie REDescent 16oz Fluorescent Latent Print Powder may be used on the same surface types as non-fluorescent powders. Fluorescent latent print powder 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.
