For many color measurement tasks it is important to determine the color temperature of luminous objects. According to DIN 5031-P.5, the color temperature TC (K) of a radiator requiring characterization is the temperature of a Planckian radiator at which it emits radiation of the same color type as that of the radiator being characterized.
The calculation of color temperature is performed using an algorithm according to Qiu Xinghong, which enables very good research results for the color temperature range from 1667°K to 25000°K to be obtained.
The color temperature is calculated and displayed by both Gigahertz-Optik color measurement systems (P-9801 with CT-3701 head or HCT-99 with CT-4501 head. see here below).
