ABSTRACT:
A viewer system and method for evaluation of fluorescence of a test sample in comparison with a standard is provided. The system includes a viewer and test sample. The viewer has a fluorescence standard, a platform, a shield and an ultraviolet light source. The platform is positioned below the standard, the shield is adapted to enclose the viewing area and the ultraviolet light source is adapted to substantially simultaneously and equally illuminate the sample while the sample is supported in the viewing area by the platform. The sample is positioned for evaluating the fluorescence of the sample in comparison to the standard in the viewing area while the sample and the standard are substantially equally illuminated by the ultraviolet light source. The viewer system and method 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.
