Abstract
In accordance with a broad aspect of the present invention the system and method described are directed to correcting with a single reference channel thermally dependent spectrum shifts of a light source used with a spectrophotometer. In one embodiment of the system and method described, a light measuring device uses the measured light intensity values to generate a correction coefficient for use in correcting measured light from an object under analysis.
