Abstract

A housing (500) for a wire grid polarizing beamsplitter (240) and a spatial light modulator (210) in alignment with an output optical path has a front plate having an opening (502) for admitting incident illumination and a modulator mounting plate (506) for mounting the spatial light modulator (210) in the optical output path. First and second polarizer support plates (512, 520) extend between the front plate and the modulator mounting plate (506), with their respective facing inner surfaces providing coplanar support features for supporting the wire grid polarizing beamsplitter (240) within a fixed plane. The coplanar support features allow rotation of the wire grid polarizing beamsplitter (240) with respect to the output axis. The wire grid polarizing beamsplitter (240) has its surface at a fiE5d angle with respect to the surface of the spatial light modulator (210), the angle defining an output optical axis along the output optical path.
