Product Details
Faraday Crystals Terbium gallium garnet TGG Crystal
The terbium gallium garnite (TGG) crystal has high magnetooptic
constant, low optical loss, high thermal conductivity and high
laser damage threshold.TGG single crystal is the best
magneto-optical material for making Faraday polarizers and
isolators with applicable wavelength of 400~1100nm(not including
470~500nm).It's main Applications are:Faraday Rotator;Magnetic sensor and Optical Isolator.
