Xenon Illuminator Systems for 35mm and 70mm Projection

A. T. Puder, D. Mortensen

An illuminator system designated XTL (Xenon Twin Light) for projection of 35mm and 70mm motion pictures uses a regulated solid-state power supply and an illuminator with a split optical system. Maximum light output and a uniform flat light field are achieved with the optical arrangement. The XTL system supplies up to 25% more usable light compared with equivalent wattage systems.
