Zero Order Waveplate
The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction. Zero order waveplate shows better performance than low/multiple order waveplates. It has broad bandwidth and a lower sensitivity to temperature and wavelength changes. It should be considered for more critical applications.
It is constructed of two low order waveplates with their axes crossed. Thus,the effect of the first plate is canceled by the second,except for the residual difference between them. There are normally three different structures as follows,
Optical Contact
Cemented by Epoxy
Air spaced
Low Order Waveplate
Low(multiple) order waveplate is designed to give a retardance of several full waves, plus the desired fraction. This result in a single, physically robust component with desired performance. However, even small changed in wavelength or temperature will result in significant changes in the desired fractional retardance. They are less expensive and find use in many applicatios where the increased sensitivities are not an important.
Photonchinas waveplates fabrication starts from quartz materials cutting with their axes oriented within a few arcminutes before being polished to a laser-quality finish, arcsecond parallelism, and

United Photonics Technology Waveplates Principle Application 4 Waveplate UPT quarter waveplates create a quarter-wavelength phase shift 2, 90 and can convert linear polarization to circular polarization and vice versa. They are often used with a linear polarizer to form an isolator, blocking light reflected back from other surfaces (ellipsometry, optical pumping, isolation). UPT half waveplates retard one polarization direction by half a wavelength 180, effectively changing the direction of linear polarization, depending on the orientation of incident linear polarization with respect to the crystal axis. Therefor they can be used as continuously adjustable polarization rotators e.g. in electro optical modulation or as a variable beam splitter when used in combination with a polarizing beam splitter.
