Abstract
A goniophotometer was developed for use in measuring the diffusion characteristics of rear projection screen materials. Rear projection screens provide a wide range of possible diffusion characteristics. Similarly, different applications require different characteristics. The goniophotometer will facilitate the selection of screens most suitable for a particular application. Primary components of the device include a light tight chassis, a light source mounted on an arm which can be rotated plus or minus 60 degrees, a holder for screen specimens, a specifically designed photometer, and two interior ambient light panels and associated interior foot candle meters. Schematics, wiring diagrams, and drawings necessary for the fabrication of additional units are included.
