- Intended to rotate beam polarization plane strictly to an appropriate angle using the circular birefringent effect
- Made of crystalline quartz
As compared to waveplate, a rotator has an intrinsic advantage, being independent of rotation around its own optical axis. It needs no adjustment, only to be installed normal to the incident radiation. A polarization plane rotator is normally used for the specific wavelength. It is only slightly dependent on ambient temperature.
