摘要	The extreme ultraviolet (EUV) solar telescope is one of the most important instruments to observe the solar dynamics. Fe-IX/X (=17.1 nm) and He-II (=30.4 nm) are fundamental spectral lines to the research of solar corona and are always be chosen by the EUV normal incidence solar telescope. A kind of multilayer was designed in order to realize reflecting 17.1 nm and 30.4 nm spectral at one mirror. According to the chosen principle of the EUV band, three materials, namely Si, B4C and Mo, are chosen to form two superposed period multilayers. The number of the periods and film thickness are optimized. The reflectivity of the optimized multilayer is calculated by computer. The feasibility of reflecting 17.1 nm and 30.4 nm at one mirror has been proved in theory. The multilayer is deposited on silicon slice by magnetron sputtering coating machine. The multilayer is measured by laser-plasma reflectometer. The results show that the reflectivities of the multilayer at 17.1 nm and 30.4 nm are 19.9% and 20.2%, respectively. Using correct filter, such as Mg filter or Zr filter, can reflect the single spectral line at 17.1 nm or 30.4 nm.
