Product Details
High Thermal Conductivity Faraday Rotator TGG Crystal
Faraday polarizer is composed of the TGG crystal rod and a
specially designed magnet. The polarization of the beam through the
magneto-optical materials deflexed and direction of the deflection
only has some relations with the direction of the magnetic field
and has nothing to do with the direction of the beam propagation.
An optical isolator is an optical component which allows the
transmission of polarized light in only one direction.
Applications:
Faraday Rotator
Faraday polarizer
Magnetic sensor
Faraday Isolator
