Title: Extension of the NIST tristimulus colorimeter for solid-state light source measurements
Published: May 29, 2009
Abstract: In order to obtain improved color measurement uncertainties for solid state light (SSL) sources, the second generation tristimulus colorimeter of NIST has been extended with a fifth channel to perform efficient matrix corrections for the spectral mismatch of the realized the channels. It is described how the tristimulus values can be determined using detector-based calibration and matrix corrections. Using modelling, the accuracy of the spectral mismatch corrections from both the detector-based calibration and the matrix corrections is compared.
