These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookMeasuring Aspheres: Selecting the Best Technique: The metrology method should match the nature of the part and the inspection constraints.The benefits of aspheric lenses are numerous: They allow for a reduction in spherical aberrations and are ideal for focusing or collimating light, as they can achieve a low ƒ-number. Aspheres...Photonics HandbookAspheric Lenses: Optimizing the Design: 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.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...Photonics HandbookPlastic Optics: Specifying Injection-Molded Polymer Optics: The versatility of polymer optics opens new doors for optical designers who understand the whys and hows of specifications.The use of precision polymer optics is becoming an increasing necessity today as products demand sophisticated light handling components to achieve desired results.
