Schwarzschild objective
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°). WebSchwarzschild objectives are increasingly used in the EUV spectral region as imaging optics because of their large aperture, high mechanical stability, and freedom from chromatic aberrations. An EUV Schwarzschild objective is made of a primary and a secondary Mo/Si coated multilayer mirror, on which both spheres and aspheres can be used. ...
