OPTICAL WAVEPLATES

ZERO-ORDER WAVEPLATES
WP ZH/ZQ SERIES

The waveplate resolves a linear polarized light wave into two orthogonal, linear polarized components and produces a phase shift between them. It functions in an optical system to modify and control the relative phase of constituent beams.

A waveplate is also referred to as a linear phase retarder, or as a retarder plate.
In principle, the retarder or wave plate causes the phase of one of the constituent coherent polarization states to lag behind the other by a predetermined amount. An optical waveplate introduces a delay in propagation for light polarized in one direction relative to light polarized in an orthogonal direction.

LOW-ORDER WAVEPLATES
WP LH/LQ SERIES

The low 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.

Low Order Waveplates are much better than the multi-order waveplates because of its thinner thickness(less than 0.5mm), better temperature(38degC), wave length(1.5nm) and incidence angle(4.5deg) bandwidth and high damage threshold. These properties make it widely used in common applications.

ACHROMATIC WAVEPLATES
AWP SERIES

Achromatic waveplates are designed using two different substrate materials with compensating retardances and dispersions of retardance. Thus, the net birefringent phase shift is held constant over a 300-nm bandwidth with a polarization purity of better than 30:1.

BROADBAND POLYMER WAVEPLATES
MLWP/PPWP SERIES

An alternative to crystal quartz or achromatic plate retarders for low energy visible and near-infrared applications, Polymer is fairly impervious to changes in wavelength or angle of incidence.

PHASE-RETARDATION PLATES
PRP SERIES

A retardation plate is an optically transparent material which resolves a beam of polarized light into two orthogonal components; retards the phase of one component relative to the other; then recombines the components into a single beam with new polarization characteristics.

BEREK COMPENSATOR PLATES
BCM SERIES

The Berek Compensator is an optical device that is capable of quantitatively determining the wavelength retardation of a crystal, fiber, mineral, plastic film or other birefringent material.

Provided the thickness of the material can be measured, a Berek compensator can be utilized to ascertain the birefringence value. The compensator operates by measuring the rotation angle of a calcite or magnesium fluoride optical plate cut perpendicular to the optical microscope axis.
