Abstract: Projector illumination is produced by one of two basic types of optical systems, the first being the True, or Classical, Condenser System, and the second, a Source-Imaging System. Theater motion-picture illumination is not produced by classical condensers, but rather by source-imaging systems, which have specific characteristics limiting the light on the screen edge. Some of these characteristics are often produced by using short-focus lenses with a mirror designed for long-focus lenses. This produces difficulties which are not completely overcome by faster lenses. Tube sizes and spaces in projectors, meant for long-focus lenses, also frequently produce uneven illumination.
