Abstract
Recently there is high demand on earth observation with Cubesat. Usually the researcher only uses general COTS on board camera with Cubesat on its purpose. However, if the researcher needs more resolution or different wavelength, it needs custom designed telescope for it, but telescope needs high accurate optics components and its aligned accuracy. Creating a specially designed optical telescope not only costs enormously, but also takes time from design to manufacture. Furthermore, if the processing accuracy in optical processing and the accuracy in the degree of adjustment in the assembly adjustment stage are ensured, higher-precision design, processing, and assembly adjustment are required. When using Cubesat, considering how to shorten the time from kick-off to launch, and considering the short lifetime due to low orbit, it is important to build a system that can acquire fast, cheap, but high-definition images. In this study, we aimed to achieve higher resolution even with a limited optical element configuration by combining the optical design of the reflection system and the refraction system. Furthermore, by simplifying the assembling adjustment process as much as possible, a low cost and quick manufacturing was sought.
