Quartz Waveplate -- Octadic/ Quarter/Half Waveplate--Circular/Quadratic Waveplate

Photonchina

OVERVIEW

Waveplate is an optic in which the polished faces contain the optical axis. All light incidents normal to the surface are composed of components polarized parallel and perpendicular to the axis. In such a device, light polarized parallel to the axis will propagate slower than light polarized perpendicular to the axis. As the light propagates through the optic, the phase shift between the two components with various thickness. The phase shift is called retardance. The most popular retarders in Photonchina are quarter and half wave.

With an appropriate choice of thickness, any degree of retardance may be achieved at any wavelength for which quartz is transparent. However, the minimum thickness necessary to achieve a mechanically strong part corresponds to several full waves of retardance.

Photonchina’s waveplate can transmit light and modify its polarization state without attenuating, deviating, or displacing the beam.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.

Production

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.
