Realization of Total Spectral Radiant Flux of an Incandescent Lamp with Three Spectroradiometer Configurations
摘要
In an attempt to realize the total spectral radiant flux (TSRF) scale from spectral irradiance and total luminous flux, a study has been carried out to determine the suitability of the spectroradiometric configurations for sphere spectroradiometric measurements. Three spectroradiometric configurations have been studied and spectral irradiance measured from all the configurations was used to derive the TSRF scale, which has been used for the calibration of sphere-spectroradiometer system. Total luminous flux of a set of test lamps was measured under all three calibrations. Ananalysis of the measured total luminous flux has been done to ascertain the suitability of all the configurations for deriving TSRF from the spectral irradiance.
