ABSTRACT:
A test system viewer for fluorescence evaluation has been designed to facilitate the simultaneous evaluation of multiple test samples, to provide consistency in the process for the evaluation of the fluorescence and to protect the operator from the harmful effects of the ultraviolet radiation associated with the viewer.
The viewer contains a base and a viewing shield, with the base having the fluorescent light source and an internal fluorescent standard. The viewing shield contains an internal ledge and a viewing area with a fixed viewing angle to the internal fluorescent standard. The internal ledge and the viewing angle cooperate to block ultraviolet rays from the fluorescent light source and to prevent the operator from directly viewing the light source during operation of the viewer. The use of a fixed light source, internal standard, viewing area and viewing angle insures observation consistency during the evaluation procedure.
