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