    Patent number: 7413315
    Abstract: An assembly for use in a projection system includes a plurality of optical elements, such as one or more mirrors, a light engine, and a screen, and a monolith. The optical elements are coupled to the monolith to provide a central element of reference, thereby enabling alignment based on the central element of reference.

  • Arbitrary surface optical element and method of making the same
    Patent number: 7324734
    Abstract: An arbitrary surface optical element, such as a mirror for use in a rear projection television, includes a non-optical portion and an optical portion. The non-optical portion circumscribes the optical portion and has a thickness greater than the optical portion. Accordingly, the two portions cool at approximately the same rate, thereby minimizing warpage from differential cooling.
