ABSTRACT:
Complex aspheric optical surfaces may be made reliably and relatively rapidly by a method in which one surface of a relatively thick glass block is ground and polished to the desired aspheric surface, which may be tested in a system including master optics of the remaining components. This master die block may then be used to generate reverse die plates by drawing thin glass blanks against the configured surface thereof and polishing to an optical flat. These reverse die plates are then mounted on a base die block and deformable glass blanks are drawn against the configured surface thereof and the opposite surface polished to an optical flat. Upon removal, the glass blanks assume a curvature identical to the original aspheric surface of the master die block.
