The 05RP32-780 True Zero-Order Wave Plate consists of a birefringent polymer film cemented between two high-precision, high efficiency, broadband antireflection coated N-BK7 windows. This construction ensures excellent transmitted 780 nm wavefront quality and λ/2 retardation, while minimizing beam deviation and surface reflection losses. The assembly is mounted in a 12.7 mm outer diameter black anodized aluminum housing for protection and ease of mounting and has a 5.1 mm clear aperture. The wave plate fast axis marked for alignment reference. Polymer wave plates offer benefits over quartz wave plates such as better angular acceptance and less sensitivity to wavelength change. Polymer wave plates have excellent angular field of view. Retardation changes by less than 1% over a ±12° incidence angle. The polymer material has very low birefringence that is nearly constant with wavelength.


05RP32-780真零阶波板由双折射聚合物膜胶结在两个高精度、高效率、宽带防反射涂层的N-BK7窗口之间组成。这种结构确保优秀的780海里质量和λ/ 2波前传播障碍,同时最小化梁偏差和表面的反射损失。该总成安装在12.7 mm外径的黑色阳极氧化铝外壳中，以保护和便于安装，并且具有5.1 mm的透明孔径。波板快轴标记为校准基准。聚合物波板比石英波板具有更好的角度接受性和更少的波长变化敏感性等优点。聚合物波片具有良好的角视场。缺陷变化不到1%在12°±入射角。聚合物材料具有非常低的双折射，几乎是恒定的波长。
