The invention relates to a method for producing at least one optical component, comprising the following steps: a) providing at least one cavity (2), where the at least one cavity (2) is delimited on a first side by a surface (3a) of a first film part (3), where the shape of the first film part (3) is adjustable; b) filling the at least one cavity (2) with a material (4) to form at least one optical component (1) wherein the material (4) contacts the surface (3a) of the first film portion (3); c) adjusting the shape of the first film portion (3); d) curing the material (4) filled into the at least one cavity (2) such that the material (4) forms a first interface (e.g. A first optical surface) (1a) of the at least one optical component (1), the first interface (1a) comprising a shape delimited by the shape of the surface (3a) of the first film portion (3). 本发明涉及一种用于生产至少一个光学部件的方法，包括下列步骤：a)提供至少一个腔(2)，其中至少一个腔(2)由第一膜部分(3)的表面(3a)划界在第一侧上，其中第一膜部分(3)的形状可调整；b)将材料(4)填充至至少一个腔(2)中，以形成至少一个光学部件(1)，其中材料(4)接触第一膜部分(3)的表面(3a)；c
