OPTEK Technology introduces its color sensor kit that provides a simplified means of evaluating colors in various applications. The kit includes the OPB780 Series sensor, a full color sensor with 4 different frequencies relating directly to a specific color seen by the sensor. The color sensor uses a programmable light-to-frequency converter that combines 64 configurable silicon photodiodes and a current-to-frequency converter on a single monolithic CMOS integrated circuit. This sensor can recognize colors over the full 300 to 1,100 nm wavelength. Typical applications include pill sorting machinery in pharmaceutical applications, ink and/or paper color detection for office machines, color printer calibration sensors and color-match sensing in paint, textile and cosmetic manufacturing.
