Large dimension optics

摘要

1. Introduction of computer polishing machines has improved the flatness correction obtained on large optical components in different fields of activity (Astronomy, High Power Lasers, Space Activity, X-ray Mirrors for Synchrotron). It is now possible to produce off-axis aspheric mirrors with incidence angle greater than 20 degrees or aspheres with aperture number greater than F/1. 2. To produce optics for Fusion by laser or large telescopes projects special machines or facilities have to be designed and installed. We will show the kind of studies, which are done in order to be able to produce these components as serial products and show some statistical results of flatness errors achieved on a production of 400 by 400 mm~2 flat windows.
