A light polarizer includes a plurality of discrete layers of birefringent film disposed in superposed relation on a transparent substrate. The planar components of the optic axes of each successive one of the discrete layers are angularly offset relative each preceding one of the discrete layers by a predetermined angle in one or either a positive or negative direction to provide the light polarizer with selectivity for either right-handed circularly polarized (RHCP) or left-handed circularly polarized (LHCP) incident light. In another aspect of the invention, the layers are of quarter-wave thickness having planar components orthogonally offset to provide selectivity for either right or left linearly polarized light. In a still further aspect of the invention, an optically isotropic layer of quarter-wave thickness is disposed between adjacent birefringent quarter-wave plates.
