TSAG (Terbium Scandium Aluminum Garnet) – Magneto-optic Crystal – Customized Products
TSAG crystals are also known as Terbium Scandium Aluminum Garnet crystals, with the chemical formula Tb3Sc2AI3O12. They are ideal for visible and infrared light magneto-optical crystals.
TSAG crystals have high Verdet constants, and excellent thermodynamic and mechanical properties. They are used in a wide range of applications, such as Faraday spinners, isolators, and imaging applications.
TSAG Faraday crystals are used in the 400 – 1600 nm wavelength range. They have a larger Verdet constant (20% higher than TGG) and a lower absorption coefficient (30% lower than TGG) than TGG, making it ideal for compact magneto-optical devices.
