We consider the problem of calculating a refractive surface generating a prescribed
irradiance distribution in the far field in the case of a point light source. We show that this …

We present a unified mathematical framework for sixteen fundamental optical systems. The
systems have a parallel or point source and a parallel, point, near-field or far-field target …

The direct formulation of a freeform optical surface for producing a prescribed irradiance
from a point source is very complicated. Instead of directly determining the freeform optical …
