Abstract

Systematic design of a well corrected broadband refractive lens system is described. We approach the design solution beginning from an appropriate starting point that is the Lister-Petzval form with two positive groups separated by an airspace. By identifying the limiting aberrations at each phase, additional lens elements such as an image side field flattener and a quasi-concentric meniscus lens are added. We also methodically consider the performance improvement with the conversion of the quasi-concentric meniscus into a bi-aspherical element. The impact of the biaspherical element on aberration correction potential of this lens form, along with glass considerations for effective color correction are detailed.
