1920/2000/2070 nm Polarization Maintaining Faraday Mirror

The Polarization Maintaining Faraday Mirror is a passive device that provides 90 degree rotation regarding the polarization state of the input light. The PMFM offers excellent performance including the lowest possible insertion loss and environmental stability. It is used in amplifiers, fiber lasers and fiber instruments to minimize the polarization effect.
