product description

The GKER Photonics 1064 nm Polarization Maintaining Faraday Mirror (GK-PMFM Series) is a specialized passive optical component designed to rotate the polarization of input light by 90 degrees. This rotation is crucial for minimizing polarization-related effects, making the PMFM an indispensable component in high-precision optical systems. Operating at a center wavelength of 1064 nm, it is ideally suited for applications in amplifiers, fiber lasers, and various fiber optic instruments where maintaining polarization is critical.

Engineered for superior performance, the GK-PMFM Series offers a typical insertion loss of just 2.8 dB, ensuring minimal signal degradation. The Faraday Mirror also features a minimum extinction ratio of 20 dB, which helps maintain the integrity of the polarization state throughout the system. The device is built with PM 980 Panda Fiber, known for its high polarization-maintaining capability, and can handle a maximum continuous wave optical power of 150 mW.

In addition to its high performance, the 1064 nm Polarization Maintaining Faraday Mirror is designed for excellent environmental stability, operating reliably within a temperature range of -5°C to +50°C. Its robust design, combined with low polarization-dependent loss and minimal polarization mode dispersion, ensures that this device provides consistent and reliable performance in even the most demanding optical applications.
