Program

Freeform optics is a growing are in the field of optical design.  It typically denotes optical surfaces that are not rotationally symmetric, and such surfaces are increasingly being used in both imaging and nonimaging systems.  There are three facets to the use of freeform surfaces: design, fabrication, and testing.  Fabrication methods for freeform surfaces have paced this field, but design and testing methods are also quickly advancing.  The focus of this conference is design methods, but there are also talks on fabrication and testing.  This conference starts with a plenary by Prof. Jannick Rolland followed by informative talks to introduce the audience to the field.  Following there are two sessions dedicated to imaging optical design, two to illumination design, one each for fabrication and testing methods, and as session on special and emerging topics in the field.  Additionally, there is a single poster session for the congress, in which there are a number of freeform optics offerings.  A number of invited talks span the three days of this engaging conference, including presentations on aberrations of freeform surfaces, imaging and nonimaging design methods, beam shaping, manufacturing techniques, direct measurement of surfaces, and dynamic freeform surfaces.  This meeting will bring together these three communities to discuss this exciting field of optical engineering.

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.
