Quartz Waveplate --ture zero order/ zero order/ mulitple order
Description
Photonchina’s 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 <λ/10 wavefront. Their thickness tolerance is a only small fraction of a micron. To verify retardation tolerances, specially-trained optical technicians use purpose-built test gear. After anti-reflective coating, zero order and achromatic waveplates are matched in pairs and accurately aligned to each other within their cell mounts.

Applications
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,

Photonchina's 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 <λ/10 wavefront. Their thickness tolerance is a only small fraction of a micron. To verify retardation tolerances, specially-trained optical technicians use purpose-built test gear.
A half waveplate rotates linearly polarized light to any desired orientation. The rotation angle is twice the angle between the incident polarized light and optical axis. It is ideal for applications requiring high damage thresholds and retardation stability over temperature change, such as for use with lasers or infrared light sources.
A waveplate is an optic in which the polished faces contain the optical axis. It can transmit light and modify its polarization state without attenuating, deviating, or displacing the beam.
A zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction. It has broad bandwidth and a lower sensitivity to temperature and wavelength changes. It should be considered for more critical applications.
Photonchina offers octadic waveplate (1/8 waveplate), quarter waveplates (1/4 waveplate), half wave plates (1/2 waveplate), and full waveplate. Both circular aperture and quadratic aperture are available.
