Polarization Rotator
Polarization rotators are used for rotating the polarization axis of a linearly polarized light beam by a specified angle. Such control over the polarization angle is required for a variety of applications, including ellipsometry, polarimetry, scattering measurements and component testing. Broadband Fresnel Rhombs Polarization Rotators, Quartz Polarization Rotator and common half waveplate are used for such polarization angle ratation.
Quartz Polarization Rotator
A crystal quartz polarization rotator is made so that light propagates along the optic axis. Quartz Polarization Rotator rotates the input polarization proportionally to the optical path. Quartz rotator's rotatory power is a function of wavelength, varying nearly as the inverse square of the wavelength. A practical feature of rotators is that unlike half wave plates their rotation is independent of orientation. Another feature is that in contrast to quarter wave plates their action is undone upon a second transmission in the reverse direction. Thus it can be made cumulative upon repeated passes only in the same direction, as in ring lasers. It is relatively insensitive to temperature.
Features of Zero-order Waveplate
- Wide spectral bandwidth
- No angle rotation is needed
- Large sizes available(Φ6")
