LBTEK offers Faraday Rotators with various center wavelengths. When incident light enters the rotator in the forward (or reverse) direction, the polarization plane of the incident light rotates due to the Faraday effect. The rotation angle θ=V*B*L, where V is a constant related to the transmission medium, generally referred to as the Verdet constant; B and L are respectively the magnetic flux intensity component along the light propagation direction and the medium length. LBTEK Faraday Rotators provide non-reciprocal rotation while maintaining the polarization state characteristics of the incident beam. When the incident light passes through the Faraday rotator in the forward or reverse direction, its polarization plane will rotate 45° in the same direction, with the specific rotation direction depending on the medium properties and magnetic field direction. It should be noted that the magnetic field intensity and Verdet constant of the magneto-optical crystal will decrease as the temperature rises. It is recommended to use the device within a temperature range of 10°C-30°C. LBTEK also provides customization options for center wavelength, clear aperture, average power, and more.
