Abstract
The Spectra® Film Gate Photometer consists of a readout unit and a series of probes which are inserted in the film gate of color printers; one of these probes is described in detail. The probe is designed to monitor and help maintain optimum performance (color balance, density and uniformity) of continuous printers. It measures the average irradiance (exposure) through red, green and blue filters, and also measures the illumination uniformity in ten small increments across the width of the 35mm aperture. The ability to check both illumination uniformity and average exposure level in a single device is made possible by use of a unique electrooptical design which utilizes a segmented photodetector in conjunction with electronic scanning.
