Designed for 1064 nm fiber laser systems, this Polarization Maintaining Isolator protects laser sources by preventing back reflections and reverse signals that could affect stability or cause damage. The Isolator employs a Faraday-effect-based magneto-optic design to enable unidirectional light transmission while preserving the polarization state. With low insertion loss, high isolation, and high extinction ratio, it delivers consistent performance in amplifiers, fiber lasers, and optical test systems.

1IL is 0.5 dB higher, RL is 5 dB lower, and ER is 2 dB lower for each connector added.
2Connector key is aligned to slow axis.
3The isolation is related to the input power.Please inform us when you need high isolation and operate above 30 mW.
