EUV imaging systems usually utilizes near normal incidence optics including multilayer mirror and filter. In this paper  the space condition of the Earth's plasmasphere to confirm the expected performance of mirror and filter for this task were analyzed and some guidelines for the design of the optical elements were introduced. In order to achieve higher response at 304A and reduce 584A radiation for the optical system  a new multilayer coating of Mo/Si with UOx (x=2-3) was developed  and it is indicated that promising filter material is Al/C with a nickel mesh. In addition  we compute the reflectance of multilayer mirror based on optical constants and the transmission of the filter based on atomic scattering factor. The results show the multilayer mirror has high reflectance of 26.27% at 304 Aand low reflectance of 0.60% at 584A. Finally  the conversion efficiency of mirror coupled with filter is 6.88% at 304A and 0.01% at 584 A.
