Spectral Response Based Calibration Method of Tristimulus Colorimeters



George P. Eppeldauer


The accuracy of tristimulus colorimeters can be increased by using detector standards instead of traditional lamp standards for calibration. After high accuracy absolute spectral response determination of the color channels, spectral and amplitude corrections can minimize uncertainities caused by imperfect realizations of the CIE color matching functions. As a result of the corrections stable light sources of different spectral power distributions can be measured with an accuracy dominated by the sub tenth of a percent uncertainty of novel spectral response determinations.
