空间相机中与大口径透镜有关的结构设计分析

某空间相机镜头在光学设计时,因透过率、吸收率等原因,为了满足光学系统要求,经过各方面平衡后,其中有一片透镜比正常径厚比设计的偏薄些。在镜头总体结构设计时,单独对该镜片及与之相配的结构件进行了有限元分析和实验检测,发现不同的结构形式对镜片面形影响不同。为了解决这一问题,在实验中进行了探讨,以保证整个相机系统满足空间相机的实用要求。

Structure Design Analysis of the Aerospace Camera Lens

To guarantee optics system demands,when designed certain aerospace camera lens,we found that in different structures,Lens' optics capability is not consistent.To resolve this question,by the way of analysis,and contrasting with optics test,we found some questines worthy of discussing.To resolve these questions,we would advance the stucture design of aerospace camera lens.
