The kit's photodiode is designed to recognize ultraviolet, visible, and infrared wavelengths. The OPB780 Series is a full-color sensor with four different frequencies relating directly to a specific color seen by the sensor. The sensor can recognize colors over the full 300-1100-nm wavelength. It 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, while all 64 photodiodes are 120 x 120 µm in size and are on 144-µm centers.

Color sensor kit enables new design options in pharmaceutical, office, textile applications

OPTEK's Color Sensor Evaluation Kit Utilizes Light Reflection Technique to Easily Identify Colors

CARROLLTON, TX (January 28, 2009) -- Providing design engineers with a simplified means of evaluating colors in various applications, TT electronics OPTEK Technology has developed a color sensor evaluation kit. The kit includes the OPB780 Series sensor, a 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.

"The OPB780 Kit easily interfaces with computers to provide a frequency output for each sensor diode configuration," said Alan Bennett, vice president of sales for OPTEK Technology. "Utilizing a light reflection technique, the design kit provides engineers with a simplified means of identifying colors far beyond the human visual spectrum."

The OPB780 Series color sensor can recognize colors over the full 300nm to 1100nm 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.

The color sensor consists of a white LED for illumination of the target; 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, while all 64 photodiodes are 120µm x 120µm in size and are on 144µm centers.

The OPB780 Color Sensor Evaluation Kit includes:
-OPB780 sensor mounted on a test fixture;
-Interface PC board programmed to provide appropriate computer and interface outputs;
-USB A/B interface cable;
-USB flash drive with installation software, data sheet and instructions.

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

Pricing for the OPB780 Color Sensor Evaluation Kit is $125.00 each. The design kits are available immediately.
