Designing and modeling of a silver Fresnel zone plate on a film of silica nitride, designed together by IPSI RAS and St-Andrews University (Scotland) are discussed. The diameter of the zone plate is 200 mkm, border zone width is 287 nm (176 zones or 88 preriods), relief depth is 460 nm (maximum aspect ratio is 1.6), focal distance is 250 mm, calculated wavelength is 2.29 A (Cr) (quantum energy is 5.4 kEv), calculated efficiency is about 3%.
