  • Enhanced beam splitter assembly
    Patent number: 5903394
    Abstract: Measurement accuracy provided by an optical system that uses a beam splitter is maintained, by containing the beam splitter inside a housing and supplying a dry purge gas to the interior of the housing in the region of the beam splitter while the beam splitter acts on a light source of the optical system. Also, certain portions of the beam splitter where an adhesive mounting compound is applied, are masked from the light source thus avoiding contamination of the beam splitter and degradation in measurement performance of the optical system.
