Faraday Rotating Glass – Magneto-optical Glass – Customized Products
Faraday rotating glass is a magneto-optical glass with good transmittance in the visible and infrared range (520-1400nm). It can rotate the polarization plane of a beam of polarized light passing parallel to the magnetic field direction and is a glass functional material with a strong Faraday effect. Because of its “non-reciprocity”, it can rotate the polarization plane of both forward- and reverse-incident light of the same wavelength in the same direction by the same angle, regardless of the direction of light beam propagation. This material is widely used to make Faraday rotators based on these properties. TG20 has been widely used in switches, modulators, sensors, and magneto-optical isolators.
