Abstract
A wavelength shift correction system and method includes a wavelength shift correction light source that emits wavelength shift correction light including a plurality of rays of wavelength shift correction emission-line light; and a spectrometer including a spectroscopic unit that receives the respective rays of dispersed spectral light obtained by dispersing incident light in accordance with wavelength with a plurality of photoelectric converters in the dispersion direction, and outputs electrical signals corresponding to the light intensities of the rays of dispersed spectral light. When the wavelength shift correction light is measured as the incident light with the spectrometer to be subjected to wavelength shift correction, a wavelength variation is determined on the basis of the respective electrical signals output from a plurality of specific photoelectric conversion elements that receive the plurality of rays of wavelength shift correction emission-line light in the plurality of photoelectric conversion elements.
