Agiltron FRMR series Faraday Mirror is designed for fiber optic networks and measurement applications. Upon reflection, the state of polarization (SOP) rotates 90 degrees from that of the input light. The Agiltron Faraday Mirrors can help to eliminate polarization sensitivity of an optical system, such as fiber interferometers, sensors, fiber lasers, Brillouin amplifiers and fiber optic modules. The unique design and process features low insertion loss with compact size and epoxy free optical path.
