Paper Abstract

Aspheres are becoming very popular in optical design for reducing size and weight of optical systems or even allowing for novel optical performance. Innovative manufacturing enables this trend. Unfortunately, due to the type of surface form deviation introduced by CNC based grinding and polishing processes, tolerancing an optical system with aspheric surfaces becomes very complicated. Especially for serial production it is critical to know just how “good” an asphere has to be in order to guarantee the optical performance needed without overdoing it. It will be demonstrated how to overcome this limitation up to a certain level.
