AbstractA projection system, such as a slide film or motion picture projection system, includes a light source, a reflector, a film gate or aperture, and a screen. The reflector is formed from a deep-dish ellipse reflector by cutting the ellipse into at least three reflector sectors and then outwardly radially deforming the outer edges, the deformation occurring within a certain critical range. The deformed outer edges are then clamped by circular clamping means.
