1550nm Faraday Mirror

Name: 1550nm Faraday Mirror
Brand: DK Photonics
Availability: InStock

Description

The 1550nm Faraday Mirror is a passive optical component designed to rotate the polarization state of light by 45° or 90°, depending on the configuration. It utilizes the Faraday effect, achieved through a bismuth iron garnet (BIG) crystal placed in a magnetic field, to induce non-reciprocal polarization rotation. This device is essential for applications requiring precise polarization control, such as fiber optic networks, interferometric sensors, and fiber lasers. Its epoxy-free optical path ensures low insertion loss, high return loss, and robust temperature stability, making it suitable for demanding environments.

Applications include eliminating polarization induced fluctuations in fiber interferometers, Brillouin amplifier systems, fiber laser systems, and fiber optic antenna remoting systems. Our Faraday Mirror is optical path epoxy free and thus offers low insertion loss and high temperature stability.
