Abstract
A method for aligning the upper and lower centering bells of a lens doublet assembly machine is provided. In one example of the method, the method includes positioning an alignment tool with respect to a base plate of the lens doublet aligning apparatus; positioning an upper bell shaft with respect to the alignment tool, wherein the upper bell shaft includes an upper bell chuck at a lower end of the upper bell shaft; and tightening flexural bearings around an outer radial edge of the upper bell shaft, wherein the flexural bearings precisely hold the upper bell shaft into perpendicular alignment in the lens doublet aligning apparatus.
