(a) Two-dimensional map of the surface shape of a 3 × 3 mm BS with 12 bilayers and the center zoom (1 × 1 mm), having 4.2 nm r.m.s. and 0.65 nm r.m.s., respectively. Only part of the window meets the Marechal criterion. (b) Profile of the flattest 10 × 10 mm BS with five bilayers characterized with the full frame.  [article HTML]
