II-VI’s tristimulus colorimeter filters achieve high transmission in the visible wavelength range and deep blocking of near infrared and ultraviolet, to enable very high luminance measurement sensitivity and dynamic range. The filters also closely match, to within 1.2%, the target spectrum defined by the CIE 1931 standard, enabling highly accurate chromaticity measurements.
