Magneto Optical Terbium Gallium Garnet Crystal

Diameter 8.3*7.6 mm Terbium Gallium Garnet Crystal TGG Rods

Introduction :

Crystro’s TGG crystal products are prepared by the advanced and mature Czochralski (CZ) method, which has the advantages of low light absorption, good thermal conductivity, and high laser damage threshold. It is used to make Faraday rotators. The best magneto-optical material for the isolator, suitable for wavelength 400nm ~ 1100nm (not including 470nm ~ 500nm). The size of this series of TGG products can be customized according to the special needs of customers.
