Magneto-optic glass/glass Faraday rotator Tb - 20, Tb-23 and Tb - 26 is designed for laser luminous flux output control of the magnetic field in the visible and near infrared spectral range. It is used in the manufacture of Faraday rotation components based on the Faraday rotation of polarization of light, such as optical, magnetic, temperature controller, rapid optical switch, narrow, the laser gyroscope, the Angle measuring device, magnetic, optical storage and optical information processing system current measurement sensor magnetic field measurement and high voltage transmission lines, a new generation of current sensor, the wave guide, astrology, space control equipment, satellite survey and other functions.

In high power laser system, optical optoelectronic isolator is necessary, in order to prevent the destruction of the Laser Disk or other reflective laser optical components from the target. Faraday isolator is passive, one-way irreversible equipment, using the magnetic optical rotation to isolate the source from the reflection of the optical system. The isolator to protect from the optical feedback laser oscillator that Faraday isolator of key components, in many of today's laser systems.

Large aperture high glass Faraday rotator verdet constant (defined as per unit per unit path rotating magnetic field strength), is used to as a rotor material for large rotation Angle of linear polarization laser form glass in low magnetic field intensity of a given length.
