Research Abstract	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.
