About This Webinar
Freeform optics, generally defined as optics without an axis of rotational symmetry, can be very useful for increasing performance while reducing size, weight, and element count in optical systems. Examples are presented, including optics for high-volume consumer devices where polymer optic solutions can be particularly attractive. Although they can enable systems that would not otherwise be possible, freeform optics present significant challenges to designers and manufacturers. These challenges include finding a common language for design and fabrication, fabrication techniques, and especially metrology techniques. Potential solutions to some of these challenges are discussed.
