Subject of Research. The paper presents the laboratory colorimeter for determination of color parameters of objects with a diffuse reflection. We discuss design features, performance and metrological characteristics, calibration algorithm of the device in XYZ and RGB color systems. Findings for color parameters of aesthetic dentistry materials are given.Methods. The light-emitting diode and the RGB-photodiode were first used as an emitter and a photodetector in the colorimeter design. The integrating sphere with an internal baffle was also applied. Illumination distribution numerical modeling in the sphere with the internal baffle located near its center was carried out. Test samples of nanocomposites diffuse reflectors for aesthetic dentistry were examined.Main Results. The precision of measurements of color parameters determined with the use of photometer-colorimeter and the ones determined from reflection spectra within the reflection index range equal to 4-90 % was no worse than ∆X, Y, Z = 0.2. Thus, the presented colorimeter responses to the practical exploitation of the colorimetry.Practical Relevance. The presented device is being tested in Pavlov First Saint Petersburg State Medical University.
