Technology for Polarization Measurement

Faraday Rotation

Faraday Rotation is the rotation of the polarization plane when light passes through a sample in which an external longitudinal magnetic field is present. The rotation of the polarization plane is caused by the magnetic field induced discrepancy between the refractive indices for right and left circularly polarized light inside the sample.
