Lumiscope Lens-Screen System for Color Television

Article Type: research-article
Abstract: A very high-gain screen for rear projection is described. The screen makes possible the use of low-wattage projectors to provide adequate intensity for color television production. The “hot-spot” which usually appears at the center of the background-projection screen has been eliminated, making it possible to achieve high-quality color reproduction. In manufacture, a large-scale Fresnel lens is cut into a sheet of acrylic plastic. Screens as large as 76 × 102 in (193 × 260 cm) are presently available.
