Abstract: A wavelength of incident light is measured based on signals from a plurality of pixels of a photoelectric conversion element that are arranged in a dispersion direction in which the incident light is dispersed by a spectroscopic section. In correction of a shift in wavelength, a measured amount of shift in wavelength that is a difference between a measured value obtained when an emission line wavelength of incident light from a light source for wavelength shift correction that emits light including an emission line at least one wavelength in a range of wavelengths into which light can be dispersed by the spectroscopic section is measured and an original emission line wavelength is calculated. A reference amount of shift in emission line wavelength is calculated by a polynomial in which a characteristic of a wavelength shift that occurs is represented by a linear or higher polynomial with a variable indicating the wavelength or a parameter relating to the wavelength.
