Frequently Asked Questions

Photonchina's waveplates are ideal for applications requiring high damage thresholds and retardation stability over temperature change, such as for use with lasers or infrared light sources.

The most popular retarders in Photonchina are quarter and half wave.

A 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.

Retardance is the phase shift between the two components of light with various thickness as it propagates through the optic.

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.
