A device (10) for illuminating forensic depositions or other evidence that simultaneously provides output in three bands, the visible, ultraviolet and infrared. The device comprises a lamp (18) which provides light in the range of 280-1100 nanometers, a slidably mounted ultraviolet reflecting filter (24), a first rotatable filter wheel (50) provided with filters (48), and a second rotatable filter wheel (100) provided with filters (98). A highly-focused illumination system is provided by the sequential mounting and rotation on two independent axis of a large selection of wavelength and bandwidth filters. The illumination system is easily adjustable by an operator to enable the selection of particular frequencies and bandwidths for the enhanced observation of forensic subjects.
