Abstract

A device for varyingly irradiating by means of ray shaping is described. Furthermore, a method of manufacturing a structure made of a curable material by means of molding is described. In a first step of the method, a molding tool is arranged above a surface such that the curable material abuts on the surface and a molding surface, facing the surface, of the molding tool in a region between the molding tool and the surface and such that further curable material may continue to flow to the region. In a second step, the curable material is irradiated in the region in a locally varying manner such that the ray experiences ray shaping in an optical channel and such that the curable material cures at different speeds in a laterally varying manner.
