ABSTRACT:
An optical system for uniformly illuminating a plane surface using a non-uniform source of light, a focusing reflector to direct the light rays emanating from the source, and, optionally, a collimating lens. The collimating lens has its axis coincident with the axis of the reflector and is spaced from the light source so that the limiting aperture of the reflector is at or near the focal point of the collimating lens. A microwave energized source may be used to provide a non-uniform source having the desired characteristics.
