Color sensor cuts BOM/assembly costs
A six-channel chromatic white color sensor, the AS7261 provides direct XYZ color coordinates consistent with the CIE 1931 2° Standard Observer framework. It also maps the XYZ coordinates to the x,y (Y) of the two-dimensional color gamut and scales them to the CIE 1976 u’v’ coordinate system. The device’s multichannel filter set, integrated at the silicon-wafer level, offers dark, clear, and near-infrared channels, as well as the XYZ color-sensing channels.
Measurements of white light made by the AS7261 are typically accurate to within ±0.002 du’v’ in the CIE 1976 scale. The color sensor incorporates a programmable LED driver for electronic shutter control and synchronization, a UART or I2C interface, and an aperture built into its 4.5×4.7 mm LGA package that offers a ±20.5° field-of-view for high sensing accuracy.
Currently in production, the AS7261 color sensor costs $4 in lots of 1000 units.
