An XYZ Chromatic White Color Sensor

Spectral click is a multispectral light sensing device, which uses the state-of-the-art sensor IC for a very accurate chromatic white color sensing. Spectral click provides a direct reading of the XYZ color coordinates, consistent with the CIE 1931 2° Standard Observer color coordinates. It provides mapping of the XYZ coordinates to the x, y (Y) coordinates of the two-dimensional color gamut, and it scales them to the CIE 1976 u'v' coordinate system. This click board also provides accurate Correlated Color Temperature (CCT) measurements and color point deviation from the black body curve for white light color, in u'v' coordinate system. Additionally, Spectral click features the Near-IR (NIR) wavelengths sensing channel, as well as two programmable LED channels with a constant current.
