Aspheric Lenses: Optimizing the Design

Facebook Twitter LinkedIn Email Comments

This second of two articles discusses the tools optical designers need to tailor their designs to the appropriate manufacturing process, optimizing the cost of component fabrication.

Jeremy Govier, Edmund Optics, Inc.

With the understanding of aspheric lens manufacturing provided in part one of this article, designers have the tools to optimize their aspheres; the next step is to understand how to specify and tolerance the asphere so it can meet its application’s requirements. Every manufacturing process needs metrology, whether to aid in an iterative process such as magnetorheological finishing (MRF) or simply to ensure the part meets its design requirements. Testing accurately is not a simple endeavor. In the past, metrology limitations have affected asphere production capabilities as much as...Read full article
