Ion beam figuring wikipedia

An example of figuring is that used in reflecting telescope primary mirrors in a process of converting the smooth spherical mirror produced by earlier stages into the aspherical or parabolic shapes needed to form the correct image. It is done by applying different polishing stroke lengths with different sized and shaped tools. Manual figuring is a very laborious process, since the heat produced by polishing has to be allowed to dissipate before the shape of the mirror can be mea… Web1 mrt. 2016 · We proposed a simple scheme for programming scan paths of the variable-spot ion beam. It consists of three steps: rastering, grouping, and superposition, which is shown in Fig. 4. First, the ion beam scans boustrophedonically over the desired surface map or etch-depth map along a zig-zag track.
