- made of crystalline quartz
- intended to rotate beam polarization plane strictly to an appropriate angle using the circular birefringent effect
As compared to a waveplate, a rotator has an intrinsic advantage of 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.
