A complex solar X-ray and EUV imaging telescope design

摘要

We report on the concept design and the theoretical ray trace analysis of the complex solar X-ray and EUV imaging telescope (CSIT) which is composed of a grazing incidence optical system and a normal incidence optical system. The CSIT can image the full sun in the wavelength bands from 0.4 to 6 nm and one EUV wavelength of 19.5nm with the same detector. The CSIT is a compact structure and can satisfy top-level image quality requirements.
