ABSTRACT:
An illumination system is provided with at least a first arc lamp positioned on the first axis of a first reflecting device. An aspherical corrector plate is positioned to receive the light rays produced by the arc lamp. The aspherical corrector plate is shaped so that it provides a substantially constant magnification of the arc as a function of the range of reflection angles of light rays off of the reflecting device.
