The MTCSiCT Series, manufactured by MAZeT, features RGB color measurement sensors which are suitable for industrial color detection and monitoring. The sensors have steep slope of filter curves considering their typical (relative) sensitivity and limited angle of incidence. The Si-PIN photo diodes permit signal frequency of up to the MHz range, intended for taking measurements in critical situations. These devices have high temperature stability, high signal frequency, high transmission, and reduced cross talk. Furthermore, the sensors provide color and location data through their integral structure.
