Check out Ronian's air-spaced spherical doublet lens design generating uniform "top-hat" illumination from a small incoherent disk Lambertian source:
Applying the technique from above and generalizing to extended sources, Ronian derived a five-element spherical-only lens design producing uniform top hat illumination from a large (9 mm diameter) white LED:
