AI summary

A spectroscopic analyzer includes: an irradiator that irradiates a target measurement object with lights of a plurality of different wavelengths sequentially as a pre-irradiation, and, after the pre-irradiation, further irradiates the target measurement object with lights of a plurality of different wavelengths sequentially as a measurement-irradiation; a detector that, during the measurement-irradiation, detects reflected light, transmitted light, or a transmitted reflected light from the target measurement object at each of the plurality of different wavelengths of the measurement-irradiation and that outputs absorbance spectral data; a data analyzer that analyzes the absorbance spectral data; and a result display that displays analysis results related to components of the target measurement object.
