ABSTRACT:
There is disclosed a filter-grating monochromator for use in an optical analytical instrument. The monochromator is characterized by a simplified construction compared to prior art monochromators. Nevertheless, the monochromator includes features which retain the desired high accuracy, including a novel sine bar grating drive mechanism and filter change mechanism.
