空间菲涅耳透镜的材料与工艺要求分析

MATERIAL AND PROCESSING TECHNIQUE REQUIREMENT FOR SPACE FRESNEL LENS MATERIALS AND CRAFT

该文根据空间菲涅耳聚光透镜的使用要求和空间环境条件 ,比较了现有光学材料的性能特点 ,分析了材料折射率、透镜尖劈尺寸和面形误差对透镜光学的影响 ,进而对透镜成型和安装工艺提出了要求。

Based on the operation demand and space condition for space Fresnel len's characteristics of the existing optical materials are discussed in this paper.The factors which affect the performance of optic lens,such as refraction index of materials,measurement of Lenses' unit and size error,are also analyzed,Furthermore,a set of a requirement for lens' mold-making and fix-craft is raised.
