ABSTRACT:

FIELD OF THE INVENTION
The present invention relates generally to spectrophotometric instruments. In particular, the invention is an optical configuration and measurement signal acquisition and processing system for enhancing the output signal stability of a spectrophotometric instrument.
BACKGROUND OF THE INVENTION
Spectrophotometric-type instruments are known and used in a variety of applications. An instrument of this type is, for example, disclosed in the Anderson et al. U.S. Pat. No. 5,879,294. There remains, however, a continuing need for instruments capable of providing measurement to a higher degree of accuracy with relatively low levels of output signal drift.
