Abstract
In an embodiment, there is provided an apparatus. The apparatus includes an optic configured for a selected illumination application. The optic includes a first lens structure and a second lens structure. The first lens structure includes a first planar external surface configured to receive incident light, and a first internal nonplanar refractive surface opposing the first planar external surface. The second lens structure includes a second planar external surface configured to emit output light, and a second internal nonplanar refractive surface opposing the second planar external surface. The second planar external surface opposes the first planar external surface. The first internal nonplanar refractive surface and the second internal nonplanar refractive surface define a cavity. The first internal nonplanar refractive surface, the second internal nonplanar refractive surface, and the cavity are positioned between the first planar external surface and the second planar external surface. The first internal nonplanar refractive surface and the second internal nonplanar refractive surface are configured to refract received light to yield emitted light having a target output parameter corresponding to the selected illumination application.
