Abstract: A photometric device for measuring uniformity of illumination and color characteristics of light across an aperture area passing light from a light source, said device including an array of isolated light responsive elements and an associated calibration circuit for equalizing the output of each of said light responsive elements under conditions of uniform illumination. A photometer to measure illumination uniformity, average illumination, and color characteristics of light at a film gate of a continuous or non-continuous photographic or optical printer.
