PHOTOMETRIC MEASUREMENT OF AYDIN CONTROLS 8980 CRTS. TECHNICAL REPORT

This report describes measurements taken for three Aydin Controls 19-inch color CRTs. Measurements of uniformity (center and four corners for 6 colors), color (32 combinations in the center), and reflectance (at four angles) were made using a Photo Research PR-1980A photometer, with each measurement taken on two of the three units. The display units were reasonably uniform although corner luminances were always below those measured in the center, with worst case values being 76% and 65% for the two displays. Colors were fairly consistent between displays, and there were no differences due to location (other than the luminance differences just mentioned). The settings for white had a slight bluish tint to them. Reflectance was 98% for the polished glass face vs. 33% for the non-glare coated display (both measured at 0 degrees incidence). These measurements suggest the displays examined are adequate for control room use.
