    • PROBLEM TO BE SOLVED: To compensate the tilt of transmissive band characteristic for every Ch without the use of a compensation lens.
      SOLUTION: An input port inputs wavelength multiplexed light. A spectroscope element disperses the light input from the input port in angle to directions corresponding to the wavelengths. A condensing optical system condenses the light dispersed in angle by the spectroscope element. A plurality of movable mirrors are arranged in directions which are dispersed in angle by the spectroscope elements, reflect the light from the condensing optical system to the directions different from the angle dispersed in angle by variable reflection angles, and output the light to the spectroscope element via the condensing optical system. The light output from the spectroscope element is input to a plurality of output ports. Furthermore, the respective reflection faces of the plurality of movable mirrors are concave faces, having a predetermined radius of curvature, with respect to the direction of dispersion in angle of light by the spectral element.
