LENS ALIGNMENT AND POSITIONING METHOD AND APPARATUS |
摘要 |
A method and apparatus for aligning and positioning a lens such that the optical and/or cylinder axis of the lens 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, the lens apex is 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 lenses using digitized video imaging, an X-Y-Z micron stage and a microprocessor (or computer) capable of performing image analysis.
