摘要： A reflective polarzier for visible light wavelengths formed of a plurality of polarizer units. Each polarizer unit having a transparent, inorganic substrate with first and second opposing surfaces. The first surface is coated with a single layer of a dielectric material, and the second surface is coated with a layer of a highly reflective metal film or a dielectric material. The polarizer is configured to produce a “quasi-straight path,” such that a light ray exiting the substrate is substantially parallel with a corresponding, incident light ray entering the substrate. The polarizer exhibits polarization over the entire visible spectrum.
