Having the same wide rage of sensitivity as Redwop™ fluorescent powder, Black Ruby™ is an excellent primary-use magnetic powder for examination of latent prints using portable lasers, Forensic Light Sources and ultraviolet light sources. Because of it's nature Black Ruby™ Magnetic Powder is excellent as either a standard black dusting powder or a fluorescent latent print powder. It can be lifted just like any standard latent print powder, but when the surface is too rough to lift the print, simply use your Forensic Light Source or laser to flouresce the powder, and photograph it. Black Ruby™ magnetic powder is very sensitive to 570-590 nm wavelength light when viewed through a red filter.
