PROBLEM TO BE SOLVED: To suppress occurrence of reduction in optical coupling efficiency to an output spectroscopic path. SOLUTION: The optical switch comprises; a first spectroscopic section 5-1, a second spectroscopic section 5-2 which further spectroscopically analyzes a plurality of wavelength components that are spectroscopically analyzed by the first spectroscopic section 5-1, a plurality of movable mirrors 7a which respectively reflect the plurality of wavelength components that are spectroscopically analyzed by the second spectroscopic section 5-2 so as to direct the components to different directions and a control section 8 which compensates for the deviation with respect to the optical axis of the plurality of waveform components being spectroscopically analyzed by the second spectroscopic section 5-2 by the settings of the angles of the reflection surfaces at the plurality of movable mirrors 7a.
