Half Wave (λ/2) Waveplates and Retardation Plates
from Electro Optical Components, Inc.
For a given plate thickness a low order waveplate will operate as a quaterwave, halfwave and full wave plate at different wavelengths. By selecting the thickness it is possible to achieve a dual order plate giving for example, halfwave retardation at 1064 nm and fullwave retardation at 532 nm. [See More]

Waveplates (retardation plates or phase shifters) are made from materials which exhibit birefringence. The velocities of the extraordinary and ordinary rays through the birefringent material varies inversely with their refractive indices. This difference in velocities gives rise to a phase...

Unlike standard waveplates, Achromatic Waveplates, AWP, provide a constant phase shift independent of the wavelength of light that is used. This wavelength independence is achieved by using two different crystalline materials to yield quarter- or half-wave retardation over a broad spectral range. [See More]
