た実用新案登録請求の範囲(1)の光減衰器。[Claims for Utility Model Registration] (1) A Faraday element and a polarizer arranged in order from the light source side on the optical axis and whose plane of polarization changes due to a change in magnetic susceptibility, and a polarizer that magnetizes the Faraday element to change the magnetic susceptibility. an optical attenuator, the light attenuator comprising a magnetizing means, and configured to change the amount of emitted light by changing the magnetic susceptibility by the magnetizing means when linearly polarized light is incident from the Faraday element side and emitted from the polarizer. (2) The optical attenuator according to claim (1) of the utility model registration, wherein another polarizer is arranged on the light source side of the Faraday element so that the incident light becomes linearly polarized light.
