Abstract:
1. A method of producing a structure from curable material by molding, the method comprising: arranging a molding tool for an optical component, comprising: so that the molding faces the surface with not-yet cured curable material being located between the molding face and the surface and so that not the surface is distanced from the channel region with the not-yet cured curable material located between the surface and the expandable channel; irradiating the curable material in the surface region in a locally varying manner, so that the not-yet cured curable material cures at different speeds in a laterally varying manner, and during the irradiation, applying a pressure within the expandable channel of the molding tool so as to expand the expandable channel and cause a flow of the not-yet cured curable material into the surface region such that shrinkages occurring during curing of the not-yet cured curable material in the surface region are compensated for by the not-yet cured curable material.
