Electro Optical Components, Inc. Dual Wavelength Plates

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. Because of the wide range of possibilities these plates are not held in stock, but Leysop can manufacture plates to customer requirements.
