ABSTRACT:
Ultraviolet light processors containing a plurality of ultraviolet light sources are improved by providing means for increasing the intensity of one lamp to compensate for a reduction in intensity of another lamp so that the total intensity of the system is substantially the same. If both lamps are located at the first foci of a conjugate reflector system, the intensity profile will be substantially reestablished.
