Spectrometer, spectrometry, and spectrometry program for use with an integrating sphere

摘要

A spectroscopic measurement apparatus 1A comprises an integrating sphere 20 in which a sample S is located, an irradiation light supplying section 10 supplying excitation light via an entrance aperture 21 to the interior of the integrating sphere 20, a sample container 400 holding the sample S in the interior of the integrating sphere 20, a spectroscopic analyzer 30 dispersing the light to be measured from an exit aperture 22 and obtaining a wavelength spectrum, and a data analyzer 50 performing data analysis of the wavelength spectrum. The analyzer 50 includes a correction data obtaining section which obtains correction data of the wavelength spectrum considering light absorption by the sample container 400, and a sample information analyzing section which corrects and analyzes the wavelength spectrum to obtain sample information. This realizes a spectroscopic measurement apparatus, a measurement method, and a measurement program which can preferably perform spectroscopic measurement of the sample held by the sample container in the integrating sphere.
