SPECTRUM MEASURING DEVICE, SPECTRUM MEASURING METHOD, AND SPECIMEN CONTAINER

摘要

A spectral measurement apparatus for irradiating a sample as a measurement object with excitation light and detecting light to be measured includes a light source generating the excitation light; an integrator having an input opening portion through which the excitation light is input, and an output opening portion from which the light to be measured is output; a housing portion arranged in the integrator and housing the sample; an incidence optical system making the excitation light incident to the sample; a photodetector detecting the light to be measured output from the output opening portion; and an analysis means calculating a quantum yield of the sample, based on a detection value detected by the photodetector, and the excitation light is applied to the sample so as to include the sample.
