One embodiment provides for a gradient lens having a first substantially hemispherical member comprising a first convex surface and a base and a second substantially hemispherical member projecting away from the base of the first hemispherical member and comprising a second convex surface. The gradient lens also includes a plurality of gradient layers disposed within the first hemispherical member, each gradient layer concentrically aligned to the first hemispherical member and comprising an index of refraction different than that of adjacent gradient layers.

Shaped gradient lens

A gradient lens capable of focusing electromagnetic rays received at a first lens surface onto a second lens surface. The first lens surface and second lens surface can include convex surfaces protruding in opposite directions from a substantially planar surface. The lens can include a gradient index between the first surface and the planar surface and a gradient index between the two convex surfaces. The lens can include two or more gradient layers, each gradient layer having an index of refraction different than that of adjacent gradient layers. The gradient layers can focus parallel electromagnetic rays incident on the first surface onto a focal point at the second surface of the lens. As the parallel electromagnetic rays pass from one gradient layer to the next, the rays are redirected toward the focal point.
