Abstract

A refractive optical component has a main body with a plurality m of optical layers extending between a front side and a back side, each layer having a thickness, wherein each of the layers extends over a region common to all layers, the common region being greater than the maximum thickness of the respective layer by at least a factor of 10, wherein the thickness of the layers varies over the extent thereof transversely to the principal axis, and wherein the main body has a refractive index curve (n=n(x, y, z)), modulated at least in the direction parallel to the principal axis, with a plurality of maxima and minima, a distance between adjacent maxima and minima ranging between 0.5 μm and 100 μm and a refractive index difference Δn between adjacent maxima and minima ranging between 10−4 and 0.3.
