The studies of the earth and planetary exospheres require unique optics for its optical observation, such as a bright optics, and a high sensitivity at several emission lines. In this study a two-tiered multi-layers coated mirror is designed for the simultaneous observation of the Carbon and Oxygen ions emissions, which are the main components of the planetary exospheres. The results of the X-ray structural analysis for the evaluation of the temporal degradation at one-year interval show that the mirror remains unchanged for the layer structure and predict to hold the reflectivity at the range of the wavelengths.

对地球和行星外圈的研究需要独特的光学观测，如明亮的光学系统，以及在几条发射线上的高灵敏度。在这项研究中，设计了一种双层多层镀膜镜，用于同时观测行星外球层的主要组成部分碳离子和氧离子的发射。X射线结构分析结果表明，反射镜的膜结构保持不变，预计反射率将保持在波长范围内。
