| 摘 要： | 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。

| Abstract: | The designing considerations and procedure of hybrid refractive diffractive ultra wide angle (70°) eyepieces are presented, one is with two diffractive surfaces and another is with single diffractive surface. The factors such as the balance between aberrations, the manufacture issue of the minimum feature size of the diffractive element and the diffraction efficiency were taken into account in the design. It was shown that the performance merits, such as transverse aberration, lateral color, are greatly improved compared with the conventional Scidmore eyepiece, while the hybrid systems offer considerable reduction in the apparent size, weight and number of elements. Finally, the parameters of the diffractive surfaces were presented. |
