Abstract

Snell's law allows to find the slope of an optical surface needed to redirect a given incoming ray into a given outgoing ray. Since a prism comprises two surfaces the problem of redirecting one ray with a prism is underdetermined. In a range of situations it is possible to determine a prism such as to simultaneously match two given incoming rays into two given output rays. This allows to tailor 2D Fresnel optics for finite sources and targets. If source and target subtend equal angles as seen from the Fresnel lens, then the facets are symmetric resembling the minimum deviation configuration, which also minimizes chromatic aberration based an the dispersion in the material of the lens.
