Abstract

A method of producing a structure from curable material by molding includes arranging a molding tool above a surface, so that in a region between the molding tool and the surface, the curable material adjoins the surface and a molding face of the molding tool which faces the surface, and so that additional curable material may continue to flow into the region. The method further includes irradiating the curable material in the region in a locally varying manner, so that the curable material cures at different speeds in a laterally varying manner and that shrinkages occurring during curing of the curable material are compensated for by the additional curable material. The method further includes applying a constant pressure to the additional curable material. Moreover, a second method and an apparatus for producing a structure from curable material by molding and a molding tool for an optical component are described.
