Applications for portable color analyzers, color correction and mobile analysis devices

ams (CEO Jong-Deok Lee of Korea) announced the launch of an integrated color point sensor IC.

This sensor (AS7261 JENCOLOR® XYZ) serves as a platform for color sensing, facilitating design-in and streamlining the production process for manufacturers of professional or general colorimeters and color analyzers.

Additionally, the precision tri-stimulus XYZ color sensing capability mimics the human eye response curve known as the 'standard observer' color model represented by the CIE 1931 and CIE 1976 color mapping systems. The AS7261's white light measurement accuracy is typically ±0.002 du'v' over the CIE 1976 range.


The company says that it is differentiated from other chip-scale color sensor products because it integrates a robust and stable silicon filter set into the sensor die. Unlike conventional filters, this filter has extremely stable characteristics over time and temperature changes, and can be compensated during the manufacturing process through intelligence functions integrated into the sensor. These in-production correction processes eliminate the need for final product manufacturers to individually correct their products on their own production lines.

The AS7261 package is designed to be simple both optically and mechanically, allowing for rapid integration and system design. The company emphasized, "It is price competitive and can be applied to finished product designs by simply adding LEDs and a few other external components. It can significantly reduce design, BoM, and assembly costs compared to products using existing color sensor ICs."

This product is suitable for battery-operated products because it has low power consumption, operating at a maximum operating current of 5mA and a supply voltage of 3.3V. The AS7261 is currently in mass production, and the product is priced at $4 per unit in quantities of 1,000.
