Faraday Isolator / Rotator — a kind of magneto-optical device based on the Faraday magneto-optical effect.
Faraday Isolator can rotate the polarization direction of the polarized light to a certain angle, and the rotation direction is only related to the internal magnetic field. It has nothing to do with the light direction. The rotation angle of the standard Faraday isolator is designed as 45˚ or 90˚. A 45˚ Rotator is placed between two polarizers in a 45˚ configuration to form a faraday optical isolator. Faraday optical isolator is a kind of magneto-optical device with unidirectional light transmission, widely used in laser amplification systems, film-locked laser, and laser measurement equipment.
Our company has independently developed and produced a series of Rotators and Isolators. They are made of high-quality terbium gallium garnet (TGG) magneto-optical crystal, polarizing spectroprism, and high coercive magnetic materials. The series products have the highest isolation, transmittance, laser damage threshold resistance, and temperature application range.
