Abstract
Based on an HT voltage value of each data point applied to a light detector and a plurality of reference spectra measured, in measurement of a reference substance performed for a plurality of times, a weighting function deriver of a spectrum measuring device derives a relation between the HT voltage value (HTi) and a degree of dispersion σi of a plurality of spectral values as a weighting function (σ=f(HT)). Moreover, a numerical evaluator of the spectrum measuring device is configured to calculate a degree of individual coincidence between a sample spectrum and the reference spectrum, acquire the degree of dispersion σi by applying the HT voltage value at measuring the sample spectrum to the weighting function as a weighting value, and evaluate the difference between the reference spectrum and the sample spectrum based on the degree of individual coincidence to which the weighting value is applied.
