Foctek Photonics, Inc. Datasheets for Waveplates and Retardation Plates

Waveplates and retardation plates are optical elements with two principal axes, one slow and one fast, which resolve an incident polarized beam into two mutually perpendicular polarized beams. The emerging beam recombines to form

Product Name Notes
Dual Wavelengths Waveplate Dual wavelength waveplate is a multiple waveplate that provide a specific retardance at two different wavelengths, it's particularly useful when used in conjunction with other polarization sensitive components to separate...
Low Order Waveplates The low(multiple) 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. However,...
Zero Order Waveplate The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction. Zero order waveplate shows better performances than multiple order waveplates, it has...
True Zero Order Waveplate This type of zero order waveplate is constructed of a true zero order waveplate and a BK7 substrate. As the waveplate is very thin and easy to be damaged, the...
Achromatic Waveplate 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...
