Synopsis

Excerpt from Design, Construction, and Testing of a New High Accuracy Spectrophotometer

Off - axis parabolic mirrors are used in the monochromator and exit optics. Circular apertures are used as entrance and exit apertures in the monochromator so that a well-collimated beam is provided in the sam ple compartment. The use of off - axis mirrors also eliminates inter reflections that are present in lens systems. Since the beam is colli mated, there is no change in focus upon insertion of a plane sample as there is in a converging beam.

A large sample space was incorporated into the spectrophotometer to allow for flexibility both in type of measurement and in the methods of measurement. For example, other light beam geometries can be simu lated in this spectrophotometer. A detector and electronics that are both precise and linear were used to minimize corrections necessary for any measurement. Extensive testing described in sections II, III, and IV below was done to characterize the performance of the instrument.
