Product Description
High-Performance TGG Magneto-Optical Crystal
This Faraday rotator utilizes terbium gallium garnet (TGG) crystals with exceptional magneto-optical properties. The polarization of light passing through these materials deflects based solely on magnetic field direction, independent of beam propagation direction, making it ideal for optical isolation applications.
Key Applications
- Faraday Rotator Systems
- Optical Isolators
- Magnetic Field Sensors
- Laser Protection Devices
