Faraday Rotator Glass
TG20 is a magneto-optic glass which has good light transmittance in visible and infrared light（520～1400nm）. Compared with the magneto-optic crystal(TGG,TSAG), it is more suitable for medium and low power level lasers, and is cheaper.TG20 has been used for magneto-optical isolator, switch, modulator, sensor.
2.Has a high Verdet constant
3.Excellent Chemical durability
