Repetitive measurements made more rapidly, with greater accuracy. Computer-compatible scanning goniophotometer enables semiautomatic measurement of angular uniformity of integrating hemisphere or other large-aperture light source. Scanning mechanism eliminates need to locate photometer manually at each viewing angle. Keeps photometer pointed at center of aperture while moving it to different viewing positions. Scanning motion of x-y plotter forms raster in vertical plane. Viewing angles visualized by simply drawing line from desired point on raster to center of aperture.
