Description
458nm TGG Faraday Rotator Mirror
458nm TGG Faraday Rotator Mirror is a fiber component which can change state of polarization (SOP), the polarization light will rotate 45° when the input light passes the faraday rotator, and will rotate another 45° after the mirror turns the light back, the output light will have a polarization state rotated 90°, and orthogonal to the input polarization state. It’s widely used in Quantum Communication, Fiber Laser System and Fiber Optic Sensor. Higher power type is available upon request.
