Abstract
A housing (100) for mounting a wire grid polarizing beamsplitter (122) and a spatial light modulator (30) in alignment with an output optical path comprises a front plate having an opening for admitting incident illumination provided along an illumination axis. A modulator mounting plate ( ) is spaced apart from and parallel to the front plate, for mounting the spatial light modulator in the optical output path of the illumination axis. First and second polarizer support plates are spaced apart from each other and extend between the front plate and the modulator mounting plate. The respective facing inner surfaces of the first and second support plates provide coplanar support features for supporting the wire grid polarizing beamsplitter between the inner surfaces. The wire grid polarizing beamsplitter extends between the facing inner surfaces. The surface of the wire grid polarizing beamsplitter is a fixed angle with respect to the surface of the spatial light modulator on the modulator mounting plate. The fixed angle defining an output optical axis along the output optical path.
