Achromatic Waveplates – Cemented
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 while increasing the physical size thus accommodating larger beam diameters. As with the original series of AWP’s these AWP’s are available in different wavelength ranges.
Each is broadband AR coated for its respective range. The retardation performance is shown graphically on the page “Achromatic Waveplates – Retardation Curves”.
