<p>Spectrofluorometer (10) employing a pair of linear variable spectral filters (14, 18) to produce a three dimensional data output is disclosed. A collimated white light source (36) is used that first passes through a first linear variable spectral filter (14), then through a sample (16) where fluorescence occurs, then the resultant light passes through a second linear variable spectral light filter (18) that is oriented at ninety degrees from the first filter (14). The light is then detected by a CCD sensor (20) 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.</p> |
