Abstract
An ultraviolet imager for forensic and other purpose, e.g. for detection of fingerprints and other forensic evidence at crime scenes permits live simultaneous viewing, with live focusing adjustments, of an ultraviolet image, converted to visible light, and capture of the ultraviolet image on light sensitive film. A modified SLR camera provides film image capture and is optically coupled with a light intensifier for viewing and focusing. A preferred viewing system employs optical symmetry between the camera and the intensfier. Both the camera and the viewing system are optimized for processing ultraviolet light by employing ultraviolet transmissive lens elements and ultraviolet-reflective mirrors throughout.
