Faraday Rotator Glass

Faraday rotator glass is a kind of magneto-optical glasses with good transmittance in the visible and infrared range(520～1400nm). Faraday rotator glass is more suitable for medium and low power level lasers, and is cheaper compared with the other magneto-optic crystals such as TGG,TSAG. TG20 has been used widely in switch, modulator, sensor, magneto-optical isolator.
