The 10RP52-2B 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 λ/2 retardation over a 700 to 1000 nm wavelength range. It has a highly efficient broadband antireflection coating, in an air-spaced design. This construction ensures excellent transmitted wavefront quality, while minimizing beam deviation and surface reflection losses. The assembly is mounted in a black anodized aluminum housing for protection and ease of mounting, with the retarder fast axis marked for alignment reference. Because of the air-space design, our Achromatic Quartz-MgF2 Wave Plates have a higher damage threshold than achromatic polymer film wave plates. Achromatic Quartz-MgF2 Wave Plates are also less expensive than achromatic polymer film wave plates.

10RP52-2B消色差石英-MgF2零阶波板由晶体石英和氟化镁(MgF2)两种不同的双折射晶体组成。包含在1英寸(25.4毫米)的房地产这18毫米孔径零级波片λ/ 2阻滞在700到1000纳米波长范围。它有一个高效的宽带防反射涂层,在空气间隔设计。这种结构保证了优良的传输波前质量,同时最小化了光束偏差和表面反射损失。为了保护和便于安装,总成安装在黑色阳极氧化铝外壳中,减速机快轴标记为校准参考。由于空气空间的设计,我们的消色差石英- mgf2波片比消色差聚合物膜波片具有更高的损伤阈值。无色石英- mgf2波片也比无色聚合物膜波片便宜。
