GGG Substrate, Gadolinium Gallium Garnet Substrates for Magneto-optical Film
Gadolinium Gallium Garnet is a crystalline garnet (mixed oxide) material with numerous optical applications in addition to acting as a substrate for the growth of other carnet crystals. Crystro manufactures gadolinium gallium garnet in forms such as single crystals, ingots, boules, wafers in both standard and custom dimensions. We offer both polished (single or double sided) and unpolished forms; materials can be doped with rare earths and other elements.
