Abstract

An arc lamp illuminator for a projection system includes one or more polarization conversion prisms to laterally spread the arc image. A pair or triplet of projection lenses can be used with mirrors and field lenses to direct the arc image along separate paths to separate polarization conversion prisms to further laterally spread the original arc image. A compact arrangement of the two-path embodiment is enabled by the use of a compound light guide including a pair of arc image-sized input ports, a pair of TIR prisms for directing the arc image along a common path, and a rectangular light guide for guiding the arc images to the polarization conversion system.
