ABSTRACT:
A method and apparatus for molding precision optical quality glass elements having complex and concave surfaces requires the apportionment of relative movement between two opposing mold surfaces. First and second molds are contained within a floating alignment sleeve, thereby defining a mold cavity within which an essentially arbitrarily-shaped glass preform is placed. The first mold is moved in the alignment sleeve until stopped by a calibrated standoff. Thereafter, pressing is continued with the second mold moving in the alignment sleeve until opposing surfaces are completely formed at substantially the same time.
