Abstract
Spectrofluorometer employing a pair of linear variable spectral filters to produce a three dimensional data output is disclosed. A collimated white light source is used that first passes through a first linear variable spectral filter, then through a sample where fluorescence occurs, then the resultant light passes through a second linear variable spectral light filter that is oriented at ninety degrees from the first filter. The light is then detected by a CCD sensor for conversion into data. This arrangement provides a very simple, rugged and compact instrument that can be used almost anywhere, such as at the scene of a contamination accident.
