Using a light reflection technique, Optek Technology’s OPB780 color sensor evaluation kit recognizes colors over the full wavelength from 300 nm to 1,100 nm. The product includes the OPB780 Series full-color sensor with four different frequencies relating directly to a specific color seen by the sensor. The 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. The kit consists of the sensor, an interface PC board programmed to provide appropriate computer and interface outputs, a USB A/B interface cable, and a USB flash drive with installation software, data sheet, and instructions. Typical applications include pill sorting machinery in pharmaceutical applications, ink and/or paper color detection for office machines, color printer calibration sensors, and colormatch sensing in paint, textile, and cosmetic manufacturing. The kit’s photodiode is designed to recognize ultraviolet, visible, and infrared wavelengths. Pricing is $125.
