λ/2 Waveplates and Retardation Plates
from Newport MKS
The 10RP52-3B Achromatic Quartz-MgF2 Zero-Order Wave Plate consists of two different birefringent crystals: crystalline quartz and magnesium fluoride (MgF2). Enclosed in a 1 inch (25.4 mm) housing this 18 mm aperture zero-order wave plate has λ/2 retardation over a 1000 to 1600 nm wavelength... [See More]

from Ross Optical Industries
The low (multiple) order waveplate is designed to give a retardance of several full waves, plus the desired fraction. This results in a single, physically robust component with desired performance. However, even small changes in wavelength or temperature will result in significant changes in the... [See More]

Achromatic Waveplates provide a constant phase shift independent of the wavelength of light that is used. Achromatic Waveplates are formed by using two different birefringent crystalline material quartz and magnesium fluoride. The relative phase difference between the two axes is either λ/4... [See More]

Tower ’s achromatic waveplate (AWP) is similar to a zero-order waveplate, which is made from two pieces of crystal quartz except that the AWP is composed of one piece of crystal quartz and one piece of magnesium fluoride, MgF2. Both of these materials are birefringent, however, by proper... [See More]

from Daheng New Epoch Technology, Inc.
Crystalline quartz is frequently used for the high quality retardation applications. Air Space Quartz Zero-Order Wave plates consist of two precision polished quartz plates. The fast axes of two plates are orthogonal to each other. The wave plates are insensitive to wavelength, temperature and angle... [See More]

from Tower Optical Corporation
Tower Optical offers this second series of Achromatic Waveplates (AWP ’s) which are built using 25.4 mm substrates of crystal quartz and magnesium fluoride. These substrates are cemented together. This technique helps to control costs by reducing the number of surfaces requiring AR coating... [See More]

from EKSMA OPTICS
Zero order wave plates are used to rotate the direction of polarization (with λ/2 plates) or convert linear into circular polarization or vice versa (with λ/4 plates). Zero order wave plates are made from two thin sections which are polished to different thicknesses to have retardation... [See More]

The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction. Zero Order Waveplates show better performance than multiple order waveplates. They show a broader bandwidth and a lower sensitivity to temperature and wavelength changes and should be considered... [See More]
