Abstract
Abstract The invention relates to optical integrators and to methods of optically integrating electromagnetic radiation to produce electromagnetic radiation of uniform energy intensity distribution. The method of optically integrating electromagnetic radiation comprises the steps of dissecting electromagnetic radiation into a plurality of segments of electromagnetic radiation, reflecting the resulting segments of electromagnetic radiation resulting in reflected segments of electromagnetic radiation and directing the reflected segments of electromagnetic radiation so that a reflected segment of electromagnetic radiation intersects another reflected segment of electromagnetic radiation at a target. The optical integrator comprises a plurality of reflecting surfaces for dissecting and reflecting electromagnetic radiation thereby resulting in a plurality of reflected segments of electromagnetic radiation, the reflecting surfaces being positioned so that a reflected segment of electromagnetic radiation intersects another reflected segment of electromagnetic radiation at a target.
