Abstract
An optical system for a spectroscopic analyzer. The system has a light source, a detector and a sample cell connected in a line, and in the sample cell or between the sample cell and one of the other elements is a light chopper device. The light chopper has a rotating element in the form of a disc-shaped member or members which periodically block light from the light source and pass light during the times it is not blocked. The rotating element is driven by a motor on the outside of the structure.
