Webion beam figuring, spherical lenses could easily be processed by ion beam figuring. In general residual polishing errors on spheri-cal lenses contain long wavelength errors and are easily to be corrected with large ion beam tool sizes. Typically polishing errors get improved in Peak-to-alley (Pv v) as well as in Root-Mean-Square (RMS) by a factor WebAn ECR plasma cavity as small as a thumb. The core element of our products is a patented microwave discharge system as small as a thumb. The founders of Polygon Physics developed the first one in 2009 at a French research lab as a low cost microwave ion source for surface treatment purposes. Generally, when designing such a source, a magnetron …

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.
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… rave to benny hill musicWeb17 aug. 2011 · Any coherent reply to this would be quite exhausting.
