Abstract
A diffuser lens includes a first annular lens segment and a second annular lens segment. The first and the second lens segments are concentric. A refractive index of the first and second lens segments in a cross-section along a plane including an optical axis of the diffusor lens is described by a refractive index profile which varies in a direction perpendicular to the optical axis. The refractive index profile includes a first sub-profile, which describes the refractive index profile of the first lens segment, and a second sub-profile, which describes the refractive index profile of the second lens segment. The first sub-profile transitions to the second sub-profile at an interface. These first and second sub-profiles have slopes with opposite signs.
