In this meeting, the rapidly evolving impact of freeform optical surfaces on optical systems for both imaging and illumination will be highlighted. The scope of this meeting will feature work on the optical design of imaging systems with freeform surfaces, evolving methods for surface representation for illumination system optimization, and a perspective on the new challenges these surface present to optical testing. This conference is an evolution of the OSA Incubator meeting on the same subject held in late 2011. It provides a forum for exchanging new thinking and methods in response to the industry’s ability to create these new types of surfaces.
