Abstract
A method of manufacturing an optical component having at least one optical function, comprising: —manufacturing using an additive manufacturing process at least part of an optical element (40) by depositing a plurality of predetermined volume elements (14) of polymerizable material, a part of the optical element (40) being configured to provide at least a part of the optical function of an optical component, said additively manufacturing being performed such that the optical element (40) comprises an unfinished peripheric surface (42), said unfinished peripheric surface (42) having a relief pattern (44) formed by traces of the additive manufacturing process and having at least one depression (18) with regard to another part of the peripheric surface (42), —coating said unfinished peripheric surface (42) with a layer (50) of coating liquid (46) configured to at least partially fill the at least one depression (18).
