  • Cube polarizer with minimal optical path length difference
    Patent number: 9726897
    Abstract: The cube polarizer can have modified prism dimensions to satisfy the following equation: ? OPL T - OPL R ? < 0.5 * t * n p 2 , where an optical path length is a distance of light travel through a material times an index of refraction of the material, OPLT is an optical path length of the transmitted beam, OPLR is an optical path length of the reflected beam, t is a thickness of the substrate between the first surface and the second surface of the substrate, and np is an index of refraction of the first prism.
