Housing for a spatial light modulator

摘要

A housing ( 100 ) for a spatial light modulator ( 30 ) includes a first frame ( 102 ) for supporting the spatial light modulator ( 30 ) in the path of an incident illumination beam. A second frame ( 104 ) having an aperture ( 124 ) is fitted against the first frame ( 102 ) and provides a support element for disposing an optical component such as a compensator ( 90 ) proximate the aperture ( 124 ). The support element is rotatably adjustable about an axis.
