Terbium Gallium Garnet TGG Crystal Stick For Optical Components

Production Parameter

Brief Introduction:

Terbium Gallium Garnet (TGG) is a kind of synthetic garnet, a kind of magneto-optical crystal with a high level of thermal conductivity for Faraday rotators and isolators. It can be used in optical isolators and rotators for laser systems and in optical circulators for fiber optic systems,  optical modulators and current and magnetic field sensors.
