在传统的超广角 (70°)赛得莫尔 (Scidmore)目镜的基础上 ,设计了两个折衍混合 70°视场的目镜。其中一个混合系统含有两个折衍单透镜 ,另一个含有一个折衍单透镜。所设计的混合系统与赛得莫尔目镜进行了像差和结构的比较 ,表明折衍混合目镜系统不仅在诸如垂轴像差、垂轴色差、平均场曲等光学性能方面优于传统的赛得莫尔目镜系统 ,而且在尺寸和重量上有非常显著的减少。最后讨论了衍射面的结构参量。
Based on the traditional ultra-wide-angle (70 °) Scidmore eyepiece, two eyepieces were designed to blend and blend a 70 ° field of view. One of the hybrid systems contains two folding single lenses and the other contains a single folding lens. A comparison of the aberration and the structure of the hybrid system with the Sedentor eyepieces shows that the hybrid eyepiece system is superior to the conventional one in optical performance such as vertical axis aberration, vertical axis chromatic aberration, mean field curvature Moore eyepiece system, but also in the size and weight of a very significant reduction. Finally, the structural parameters of the diffractive surface are discussed.
