Patent ID: 8000007

Claim:
A polarization filter utilizing Brewster's angle comprising: a light receiving body having an input end with a plurality of planar facets, at least two of the plurality of planar facets being arranged at Brewster's angle relative to an optical axis along which light from an incident stimulus of collimated electro-magnetic radiation projected concurrently from a single direction onto the input end passes after striking the plurality of planar facets of the body, the plurality of planar facets are positioned in different radial orientations, relative to the optical axis, to provide simultaneous differential transmission or simultaneous differential reflection of different polarization planes in the light projected from the incident stimulus, and the different polarization planes, which are transmitted through or reflected by the plurality of planar facets are each oriented in different radial orientations relative to the optical axis, wherein the body consists of a bundle of prisms, with one of the facets at an end of each prism, at least one of the facets of one of the prisms in the bundle of prisms being oriented to reflect a first polarized component ( 12 ) in the incident stimulus with a remainder of unreflected incident stimulus being simultaneously transmitted and at least one of the facets of another of the prisms in the bundle of prisms being oriented to simultaneously reflect a second polarized component ( 14 ), other than the first polarized component, in the incident stimulus with a remainder of unreflected incident stimulus being simultaneously transmitted.
