摘要： An improvement is added to a spectroscope for performing wavelength dispersion of measured light with a wavelength dispersion element and receiving the light at a light reception element. The spectroscope has a first compound lens made up of a plurality of lenses for converting measured light into parallel light and emitting the parallel light to the wavelength dispersion element; a second compound lens made up of a plurality of lenses for gathering the measured light subjected to the wavelength dispersion in the wavelength dispersion element and causing the light reception element to receive the light; and a base for fixing the wavelength dispersion element, the first compound lens, and the second compound lens. The linear expansion coefficient of the compound focal length of the first compound lens, the linear expansion coefficient of the compound focal length of the second compound lens, and the linear expansion coefficient of a material forming the base are substantially equal.

摘要： A spectroscope includes a diffraction grating having a plurality of ruled parallel lines; and a plurality of spectroscopic paths, each of which has a collimator for collimating incident light, emits the collimated light to the diffraction grating, and emits return light, which returns from the diffraction grating, through a slit provided on the path. In the spectroscope, measured light is emitted through the plurality of spectroscopic paths so as to extract light which is included in the measured light and has a predetermined wavelength; and the collimators of the spectroscopic paths are arranged so that irradiation areas of light emitted from the collimators are offset from each other at least in a direction along the ruled parallel lines. The collimators of the spectroscopic paths may be arranged so that incident angles of light emitted from the collimators coincide with each other.
