WebWe deal with the recent progress in the fabrication of the graded Co/C multilayer mirrors to be used in a 21× Schwarzschild objective (SO) operating at the wavelengths near 4.5 nm (“carbon window” region). The peak reflectivity of flat Co/C mirrors was measured to be 14.8% (wavelength of 4.48 nm, incidence angle of 5°). WebThe Schwarzschild objective is a convex-concave mirror system in which the mirrors are approximately concentric, with the long conjugate on the convex mirror side. Originally …
Web21 Aug 2013 · The Schwarzschild objective is a widely used optics in high-resolution, small-field imaging and projection systems. When operating in the EUV/soft X-ray range, its theoretical geometrical spatial resolution is comparable with the diffraction limit. A very careful alignment is then mandatory in order to exploit the SO performances. Web18 Oct 2024 · For investigating extreme ultraviolet (EUV) damage on optics, a table-top EUV focusing optical system was developed in the laboratory. Based on a modified Schwarzschild objective with a large numerical aperture and a laser-plasma light source, this optical system can generate a focusing spot with the maximum energy density of …
