ABSTRACT:
A cabinet structure for identifying and examining objects by illuminating said objects with radiation of selected wavelengths, such as short wave ultraviolet radiation, long wave ultraviolet radiation, visible radiation, and infrared radiation is described. The cabinet structure includes a truncated pyramidal hood wherein light sources for emitting selected wavelengths of radiation are mounted on the respective sloped pyramidal sidewalls of the cabinet for illuminating a specimen mounted beneath the hood. A top surface defining the top of the truncated pyramidal hood has means thereon for mounting a camera such as a photographic camera, TV camera or the like. When it is desired to examine or photograph large documents such as oil paintings the truncated pyramidal hood is placed over the document. For smaller specimens to be examined, the hood is provided with an entrance door in one sidewall thereof through which specimens may be inserted. A back light source module may be provided which is removeably attached to the bottom of the cabinet for transmitting light through the specimen toward the camera at the top of the cabinet. The light assemblies on at least one of the sloped sidewalls of the truncated pyramid hood are mounted in cabinets, which are hinged at the bottom ends so that they may be pivoted back away from the sidewalls on which they are mounted. These sidewalls have filter windows therein with changeable radiation filters, and when the light assembly housings are pivoted back at the hinges these filters may be readily changed to achieve different selected illumination effects.
