Paper Abstract

The production task for very large metal mirrors by micromachining has been addressed by various manufacturors on this SPIE forum. We as a machine tool builder have since years focussed on providing air-bearing turn-tables of diameters from lm up to 5m diameter. With less than 1μm departure from planarity and roundness these - tables are used not only for metrology but for machining of such large mirrors specifically.
