METHOD OF MAKING AN ARBITRARY SURFACE OPTICAL ELEMENT

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...

Zusammenfassung:	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.
