Paper Abstract

The Radian Group, Inc., manufactures The Radian System, a specialized 35mm motion picture projection system producing an image on a hemispherical gray screen, typically a planetarium dome. The optical system consists of a reflector-backed xenon arc, a relay lens, field antics, and a fisheye lens. Well-considered alignment is required to simultaneously focus the image and nroduce uniform illumination.
