TB3Ga5O12 Fiber Isolator Magneto Optical Square TGG Crystal
Fiber Isolator Used Magneto Optical Materials Square TGG Single Crystal
Description:
The magneto-optical crystal TGG crystal is key material for free space faraday isolator. It's an optimum material for Faraday devices (Rotator and Isolator) in the wavelength range 400 nm-1100 nm, excluding 470-500 nm. TGG crystal has a combination of excellent properties such as large Verdet constant, low light loss, high thermal conductance and high light damage threshold which makes it a unique material for Faraday devices.
Crystro Supply TGG Crystal Boule up to Diameter 4 Inches.
It is now the biggest size available in China.
Terbium Gallium Garnet (TGG) Crystal Used for Faraday Isolators and Rotators,small size like 3x3.5x5mm can also be used in Fiber Isolators.
