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.
Photonchinas 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.
Waveplates Types:
Photonchinas waveplates include octadic waveplate (1/8), quarter
waveplates(1/4), half wave plates(1/2) and full waveplate.
Both circular aperture and quadratic aperture are available.
Half waveplate
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.
Quarter Waveplate
When linearly polarized light is input at *5deg to the axis of a
quarter waveplate , the output is circularly polarized similarly,
input circularly polarized light is transformed into linearly
polarized light.
The thickness of the quarter waveplate is such that the phase
difference is 1/4 wavelength ( λ /4, Zero order) or certain
multiple of 1/*-wavelength [(2n*1)λ /4, multiple order].
Production
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 <λ/*0 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.
