Abstract: The present invention is intended to realize a spectrometer which improves the wavelength resolution without being affected by the pitch of the photodiode array. The present invention is characterized by a spectrometer which comprises a wavelength dispersion device spectrally dividing the measured light beam and a photodiode array composed of a plurality of photodiodes that detect the spectrally divided light beams by the wavelength dispersion device and output photocurrents, and performs measurement using the outputs of the photodiode array; providing a deflecting means that deflects the measured light beams and changes the position where the measured light beams are detected by the above photodiode array, and measuring the characteristics of the measured light beam from the measured results for different deflection amounts.

Abstract: The present invention relates to a spectrometer whereby the accuracy of wavelength measurement can be improved without being affected by the environment of use. The present invention is characterized by improvements made to a spectrometer for spectrally dividing the light under measurement by transmitting the components thereof at different, wavelength-by-wavelength angles, and receiving and detecting the light under measurement thus spectrally divided by the chromatic dispersion device using an optical detector. The apparatus according to the present invention comprises a refractive index compensation means for compensating changes in the angle at which the chromatic dispersion device transmits the light under measurement, according to changes in the refractive index of the medium in which the chromatic dispersion device is placed.
