Abstract
Disclosed is an electro magnetic radiation polarization converter, available in various combinations of the embodiments features, used to convert non polarized radiation into a single polarization state, which may be utilized in many devices requiring polarized radiation. Disclosed is a unique geometric configuration and positing of optic layers that cause polarization separation by reflection and polarization conversion utilizing birefringent materials as well as phase retardation materials to convert incident radiation to a linear or elliptical polarization.
