Abstract
A converter for using a spectrophotometer as a fluorometer includes a barrier for blocking the light in a collimated beam from reaching the detector of the spectrophotometer after this light has passed through and excited a sample material. A second detector is positioned to receive any fluorscence from the material which is emitted in a direction substantially perpendicular to the path of the collimated beam. A signal, generated by the second detector in response to fluorescence from the sample material, is modified to drive a second light source with an intensity which is linearlized relative to the generated signal. The detector of the spectrophotometer then receives the output from this second light source to measure the intensity of the fluorescence.
