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 &lambda,/2 retardation over a 1000 to 1600 nm wavelength range. It has a highly efficient broadband antireflection coating, in an air-spaced design. Achromatic Quartz-MgF2 Wave Plates are also less expensive than achromatic polymer film wave plates.
