为解决传统微光夜视仪目镜系统高性能与轻量化之间的矛盾，提出了一种新型的折射/衍射混合自由曲面微光夜视仪目镜结构，以传统艾菲尔目镜为基础，应用Zemax软件设计了新型微光夜视仪目镜系统，系统由三片透镜组成，都采用K9玻璃，将设计结果与传统艾菲尔目镜的光学性能进行了比较，结果表明，新型目镜系统不仅在垂轴像差、垂轴色差、畸变、场曲等光学性能上大大优于传统目镜系统，而且在重量和总长方面也得到了较大的改善，满足现代微光夜视仪目镜小畸变、轻量化、高像质的实际需求，为微光夜视仪目镜的轻小型设计提供了一种新的思路。

To resolve the contradictions between high performance, low distortion and lightweight ,a novel eyepiece with freeform surface and diffractive surface was presented. Based on the conventional erfle eyepiece, a noel eyepiece with freeform surface and diffractive surface was designed by Zemax software. The noel eyepiece system consisted of three lenses. Only glass K9 was used in the noel eyepiece system. The optical performance of the noel eyepiece were compared with the erfle eyepiece. It is shown that the novel eyepiece not only has better performanc, as transverse aberration, lateral color, distortion and field curvature, but also has greatly improved in weight and total length, which can meet the demands of night vision eyepiece system. It also provide a new approach for lightweight and compact low-level-light night-vision eyepiece system system designs.
