Abstract:
1. A spectroscope comprising: a spectroscopic device that decomposes light from a microscope into spectra, a multi-channel photodetector that is constructed by a plurality of photodetectors and detects the spectra decomposed by the spectroscopic device, a moving means that varies a detecting position of the spectra in the multi-channel photodetector along a direction of wavelength dispersion of the spectra, and a calculating means that processes each luminance data from the plurality of photodetectors, wherein the calculating means calculates sensitivity fluctuation of each photodetector of the plurality of detectors from a first luminance data detected before varying the detecting position of the spectra in the multi-channel photodetector and a second luminance data detected after varying and corrects the first luminance data or the second luminance data.
