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°).
Web11 Aug 1994 · When using a Schwarzschild objective as a micro-exposure tool (MET) at high spatial resolution (half-pitch≤0.1 μm), in addition to the tight requirements on the design and surface figure for the single optics, also an accurate alignment between the two mirrors is needed to reach the planned spatial imaging detail. Ideally, at-wavelength … bunny girl senpai saison 2 vfWeb1 Aug 2000 · Schwarzschild objective for soft x-rays. The geometrical aberrations theory of a centered system is applied to calculate the third order aberrations of the optical system based on two spherical mirrors (the so-called Schwarzschild objective).
