Webdiameter ion beam was used. In the second experiment, the 2D RMS in a 50 mm 5 mm planar CA was reduced from 39.1 to 8.8 nm with the same 24 mm diameter ion beam after one IBF run. A 5 mm pinhole was then installed in front of the ion source, and the final 2D RMS achieved 1.9 nm after two more IBFruns. The rest of the paper is organized as … WebNow an affordable ion beam figuring technique has been developed to address precision aspherical optics applications. This paper introduces ion beam figuring technology based on equipment which is widely used in semiconductor mass production for ultra precise film thickness trimming.

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 WebIBF – Ion Beam Figuring NTG bietet eine große Auswahl an Standardanlagen für verschiedene Werkstückabmessungen und Applikationen. Darüber hinaus können Anlagen auch an kundenspezifische Anforderungen angepasst werden. IBF-Prozess cleaning advice

WebTechnology scouting. v. t. e. The future of space exploration involves both telescopic exploration and the physical exploration of space by robotic spacecraft and human spaceflight . Near-term physical exploration missions, focused on obtaining new information about the solar system, are planned and announced by both national and private ... WebThe key to improving this control is to better understand how the energetic beams influence film, surface properties and the microscopic mechanisms responsible for beam-induced effects. This book addresses growth, ion erosion, surface smoothing, texturing and pattern formation, etching, structural stabilization and stress relaxation. WebOur machines for ion beam figuring and plasma-assisted chemical etching of precise optical material were honored with awards at the INTEC international specialist trade fair in 2008 and 2009. In 2015, we successfully developed the world’s first automatic, robot-controlled loading and unloading system for ion beam correction systems. cleaning adverts
