Abstract

A light analysis system for analyzing light transmitted through an ampoule includes a housing having at least one receptacle for the ampoule, a cover for substantially preventing ambient light from affecting the receptacle and having an interior reflective surface, and a master control system. Each receptacle includes at least one light source and a photodetector positioned such that the light from the light source passes through the receptacle (and thereby the ampoule and its contents) prior to entering the photodetector. According to one preferred aspect of the invention, the receptacles are provided preferably at a 30.degree. to 45.degree. angle relative to vertical. According to another preferred aspect of the invention, the light source is at least one LED which is directed to transmit light upward into the reflective surface of the cover such that the light is reflected by the cover downward into the receptacle toward the photodetector. The master control system permits user input, operates the light analysis system, and provides a user-readable display for the output of the results of the light analysis of the contents of the ampoule in the receptacle. The apparatus may include a large number of receptacles suitable for laboratory use or may include fewer or one receptacle suitable for home or portable use. Power supply circuitry is provided facilitating the use of the apparatus in a variety of environments.
