SURFACE ALIGNMENT AND POSITIONING METHOD AND APPARATUS

摘要

A method and apparatus for aligning and positioning a surface such that the optical and/or cylinder axis of the surface is precisely aligned with a fixture for the purpose of assembly or further mechanical operations such as machining and polishing. According to another aspect of the invention, a lens apex is located and precisely positioned a constant distance from a reference point. In order to implement the above, a method and apparatus is disclosed for optically aligning and positioning surfaces using a precision laser displacement measurement device, an X-Y-Z micron stage, and a microprocessor (or computer) capable of performing curvature analysis.
