Choosing optical materials for diagnostics of the solar atmosphere in the wavelength range of 6–60 nm
We present our calculations for the reflection characteristics of multilayer mirrors for a series of wavelengths in the interval of 6–60 nm. Interest in these wavelengths is due to preparations for prolonged studies of the Sun within Russia’s ARCA project. For each structure, we suggested a relationship of material layer thicknesses in the period that ensures the optimum reflection coefficient for high spectral selectivity.
