Abstract

We provide a general formulation for the design of any dual-surface aplanatic Fresnel optic (including combinations of refractive and reflective surfaces), with categories of devices that had not previously been recognized. Raytrace simulations for representative Fresnel aplanats in collimation (illumination) mode reveal compact designs with radiative efficiencies close to those of their aplanatic continuous non-Fresnel counterparts, and optical performance approaching the thermodynamic limit for radiative transfer.
