ABSTRACT:
A thin optic electro magnetic radiation polarization converter, available in various combinations, used to convert non-polarized radiation into a single polarization state, which may be utilized in many devices requiring polarized radiation. A unique geometric configuration and positioning of optic layers that cause polarization separation by radiation concentration, reflection and polarization conversion utilizing birefringent materials to convert incident radiation to a linear polarization.
