The Past, Present and Future of Freeform Optics
Freeform optical surfaces are emerging as a path to truly three-dimensional optical designs. In this talk I will provide a short historical context to this emergence and discuss the challenges as well as the rapidly emerging knowledge that spans from the mathematics of freeform surfaces to the implementation of freeform optical systems.

E: Graphical Methods for Designing Optics in CAD
A number of simple graphical methods for designing optics in CAD are presented. These methods are based on the law of reflection, Snell’s Law, Fermat’s principle and a property of focal conics. These graphical methods will be illustrated using the practical example of designing a catadioptric LED collimator.
