PROBLEM TO BE SOLVED: To provide a spectral system which can perform spectral intensity correction for an optical system, using a calibrating light source. SOLUTION: The spectral system comprises a microscope 220, a confocal unit 230, and a spectral device 240. The microscope 220 includes a wavelength calibration light source section 225 which is placed on an optical system, which is coaxial with an objective 221 of the microscope 220 and allows wavelength calibration beam to be made incident on the objective 221. In the wavelength calibration light source section 225, a light source drive circuit 2255 applies a fixed voltage to a wavelength calibration light source 2251 to make it light.
