Abstract
Cube polarizers can be designed for substantially equal optical path lengths of a reflected beam and a transmitted beam. For example, dof FIG.can define a distance between a plane (face plane) of the outer face (outer face) of a second prismand the first edge (first edge) of the first prism, and dcan be less than 400 micrometers. As another example, an optical path length differential between a transmitted beam and a reflected beam (|OPL−OPL|) can be where t is a thickness of the substrate between the first surface and the second surface of the substrate and nis an index of refraction of the first prism.
