Multilayer supermirrors stacked with three sets of Pt/C combinations have been fabricated on a flat float‐glass and conical replica foil mirror using a magnetron DC sputtering system, and applied to X‐ray optical systems in the hard X‐ray region. The design of the supermirror is optimized to obtain the highest integrated reflectivity in the energy band and at the grazing angle concerned. X‐ray reflectivities of 30% in the 25–35 keV band at an incidence angle of 0.3° were obtained.
