Optical devices utilizing freeform optical surfaces must be used when the light sources andor targets and input andor output radiation patterns lack special symmetries. In these cases traditional designs constrained by use of a particular symmetry may lead to highly energy inefficient devices. Freeform lenses and mirrors are surfaces designed without any a priori assumed symmetry. Under this effort a unified and rigorous approach to solving wide classes of optical design problems requiring freeform optical surfaces has been developed. Computational methods for such problems have also been introduced and tested.
