Description
635nm TGG Fiber Faraday Rotator
635nm TGG Fiber Faraday Rotator is a fiber component which can change state of polarization (SOP), the output polarization light will rotate 45° or 90° when the input light passes faraday rotator, It’s widely used in Quantum Communication System and Fiber Optic Sensor. High power type is available upon request.
