Abstract
An integrating light pipe, very preferably a kaleidoscope, encloses a source of radiant thermal energy, the light pipe and energy source being so arranged as to achieve efficient and substantially uniform heating of a workpiece in a target plane. The pipe has closed ends so as to heat the workpiece from both sides uniformly and efficiently. The apparatus employs CW lamps, pulsed lamps, and a combination of the two.
