| abstract | (57) [Problem] To provide a spectroscope capable of maintaining good wavelength resolution even when ambient temperature changes. SOLUTION: Light incidence means for limiting the width of light of a light source; A first concave mirror for converting light through the light incident means into parallel light, a diffraction grating for converting parallel light into diffracted light, a second concave mirror for collecting diffracted light, and a band of the collected light And a linear expansion coefficient of a focal length of the first concave mirror in a spectroscope including a slit for limiting the distance, and a light incident means, a first concave mirror, a diffraction grating, a second concave mirror, and a substrate on which the slit is fixed. By making the linear expansion coefficient of the focal length of the second concave mirror substantially equal to the linear expansion coefficient of the material forming the base, even if the ambient temperature of the spectroscope changes from the temperature at the time of assembly, the wavelength resolution is good.
