18 Sep 2009 Foctek's Achromatic Waveplates are designed to effectively eliminate the wavelength dependence over a wide spectral range,typically several hundred nanometers. Foctek's Achromatic Waveplates are available for four wavelength ranges:VIS (450-680nm), NIR(700-1000nm), 950-1300,1200-1650.The AWPs are air spaced construction in a black anodized aluminum housing.Fast axis is marked on the mount.Custom assemblies,including cemented versions,are available to meet your specific requirements.
