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.

Spectral 2 click is a multispectral color sensing device, which uses the state-of-the-art sensor IC for a very accurate color sensing. The sensor on the Spectral 2 click provides multi-spectral sensing in the visible range of wavelengths from approximately 430nm to 670nm with the full width at half maximum (FWHM) of 40nm. Spectral click provides a direct reading of the six different color components with the 16bit precision, as well as the calibrated reading, that gives 32bit float values with an 8bit biased exponent and a 23bit fraction part, processed through the Spectral ID engine. The sensor also integrates two programmable LED channels with constant current drivers, useful for indication and for providing the backlight for the measured color object.
