Abstract

A low cost optical system which incorporates a low ultraviolet output tungsten halogen light source and solid state photodetectors and circuitry in such a way as to provide reliable fluorometric test results. The attainment of reliable results using such components is made possible by incorporating highly ultraviolet transmissive optics to maximize ultraviolet light throughput and by using solid state circuitry together with a filter wheel having both light blocking and light passing regions in a manner which fully accounts for noise and dark signals associated with solid state photodetectors.
