Abstract
In an apparatus for measuring a spectral property such as a total spectral radiant factor of a fluorescent sample, a weight factor is previously calculated by using a standard fluorescent sample in which an index of a spectral property such as a total spectral radiant factor is known. When a spectral intensity distribution of a fluorescent sample to be measured is measured, the measured spectral intensity distribution is corrected similar to a value when the fluorescent sample is illuminated as if the same illumination light when the weight factor is set. As a result, the error component in the measurement result due to the variation of the illumination light in a time period from the setting of the weight factor to the measurement of the fluorescent sample can be reduced.
