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&deg; to 45&deg; 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.

An ampoule incubator and light analyzer is provided which includes a housing having at least one receptacle for an ampoule, an incubation system, a light analysis system, and a master control system. According to the invention, the incubation system includes, for each receptacle, a heating element which heats the ampoule and a temperature sensor which senses the temperature of the ampoule. Each receptacle is preferably insulated to prevent unintended heating of neighboring receptacles of the apparatus. The incubation system is adapted to quickly heat the receptacle, and consequently the ampoule provided therein, up to the desired temperature. The incubation system is calibrated by soaking the circuits of the control system in a controlled temperature environment maintained at the desired operation temperature for analysis of the ampoules. When the circuits are at the desired operation temperature, the circuits of the incubation system are powered and switches in the circuits are closed causing a microcontroller of the master control system to store digital representations of the temperature of each individual receptacle in non-volatile memory. Then, during operation of the apparatus, the incubation system is directed to the values previously set in non-volatile memory during calibration, without necessitating expensive and error-prone trim pots, ultra high precision components, or other adjustable components.
