1064nm Polarization Maintaining Faraday Mirror 
The 1064nm PM Faraday Mirror provides 90 degree rotation without regarding to the polarization state of the input light. The FM offers excellent performance including the lowest possible insertion loss and environmental stability. It is used in EDFA, DWDM systems, CATV systems and fiber laser and fiber instruments to minimize the polarization effect.
