Abstract
A cube wire-grid polarizing beam splitter includes a pair of prisms secured together to form a cube. An array of parallel conductive wires is disposed between the pair of prisms. A pair of continuous film layers is disposed on one side of the wires between the wires and one of the pair of prisms with an intermediate film layer adjacent the prism having a refractive index greater than both i) a refractive index of a rear film layer adjacent the plate wire grid polarizer, and ii) a refractive index of an adjacent prism. A layer of ribs is disposed on another side of the wires between the wires and another of the pair of prisms, the ribs being aligned with and supporting the array of parallel conductive wires.
