Abstract

A device for illuminating forensic depositions or other evidence that simultaneously provides output in three bands, the visible, ultraviolet and infrared. By a sequential mounting and rotation in two independent axis of a large selection of wavelength and bandwidth filters, the invention provides a highly-focused illumination system easily adjustable by the operator to enable selection of particular frequencies and bandwidths for enhanced observation of forensic subjects.
