Abstract.   Basic design features and technical performance characteristics of laboratory colorimetric detector based on three-element RGB-photodiode with three optical filters for measuring of color parameters of transparent and diffuse reflective objects are considered. The detector calibration procedure is discussed. Results of test measurements carried out with colored glasses and diffuse reflectors are presented.
