Imaging with an ultra-thin reciprocal lens
WitrynaImaging is of great importance in everyday life and various fields of science and technology. Conventional imaging is achieved by bending light rays originating from … WitrynaIn optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the radii of curvature of the lens surfaces. Lenses whose thickness is not negligible are sometimes called thick lenses.. The thin lens approximation ignores optical effects due to the thickness of …

WitrynaIn this work, we present a comprehensive study on real-time monitoring the growth of epitaxial CoxFe3−xO4 thin films grown on SrTiO3(001) substrates via reactive molecular beam epitaxy. The growth process was monitored during evaporation by means of time resolved operando hard X-ray photoelectron spectroscopy (HAXPES). … Witryna4 kwi 2024 · The ED-1 features multiple magnetic lenses with variable focal lengths and a single beam-limiting aperture with a fixed aperture diameter between the electron source and the sample, designed ab initio and fully optimized for the most accurate diffraction experiments, as well as for imaging in order to visually inspect and …
