ams AS7261 Spectral Sensing Engine

×

品目

The AS7261 integrates Gaussian interference filter technology to enable chromatic white color sensor which provides direct XYZ color coordinates consistent with the CIE 1931 2° standard observer color coordinates. Additional mapping of XYZ coordinates to the x, y (Y) of the 2-dimensional color gamut and scales of the CIE 1976 u’v’ coordinate system, providing accurate correlated color temperature (CCT) measurements and color point deviation from the black body curve for white light color in the ∆u’v’ coordinate system. A near-IR channel and LED drivers with programmable currents increase application flexibility, including support for electronic shutter applications.

Control and spectral data access is implemented either through either the I²C virtual register set, or via the serial UART enabling use of the high level smart spectral command set.
