Color Sensor Evaluation Kit
Feb 2009
Optek Technology, Industrial Sensing & ControlRequest Info
CARROLLTON, Texas, Feb., 5, 2009 – To provide design engineers with a simplified means of evaluating colors in various applications, TT electronics Optek Technology has developed a color sensor evaluation kit. It includes the OPB780 series full color sensor with four different frequencies relating directly to a specific color seen by the sensor. Housed in a small lightweight package, 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.

Optek_color_sensor_kit.jpgThe OPB780 sensor can recognize colors over the 300- to 1100-nm wavelengths. 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.

The sensor comprises a white LED for illumination of the target; a photodiode array consisting of 16 green, clear, red and blue filter diodes; a current-to-frequency converter; TTL and CMOS drive circuitry; and plastic packaging with 10 pin (25.4 cm) FFC. All 16 photodiodes that have the same color filter are connected in parallel.

The OPB780 color sensor evaluation kit includes: the OPB780 sensor mounted on a test fixture; an interface PC board programmed to provide appropriate computer and interface outputs; a USB interface cable; and a USB flash drive with installation software, a data sheet and instructions.

The OPB780 kit's photodiode is designed to recognize ultraviolet, visible, and infrared wavelengths.
