Abstract
A method and a device for the production of an optical element () from a curable material by using an additive manufacturing technology. This method comprises a multiplicity of curing steps for curing said curable material inside outlines (C) whose geometry are determined according to the geometry of said optical element, by applying a curing surface energy onto the curable material that is higher in a first area (A) that extends sensibly along said sliced outline than in a second area (A) situated within the first area, the curing surface energy applied to the second area being strictly lower than a first predetermined energy threshold.
