1480nm Faraday Mirror

Name: 1480nm Faraday Mirror
Brand: DK Photonics
Availability: InStock

Description

The 1480nm Faraday Mirror is a passive optical device designed to rotate the polarization state of light by 45° or 90°, depending on the configuration. Utilizing the Faraday effect, achieved through a bismuth iron garnet (BIG) crystal placed in a magnetic field, this mirror effectively suppresses back-reflections and back-scattering. It is ideal for protecting sensitive components in fiber optic systems, such as lasers and amplifiers, from potential damage caused by unwanted reflections.

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.
