Abstract (en)
[origin: WO2013004363A1] The invention relates to a method of manufacturing an optical element (1), notably an optical element for creating a retractable sheet for use in a motor vehicle, the optical element having in the final state a three-dimensional shape that is the result of a step of forming of the optical element, the optical element being designed to have an extended shape comprising: - a first main surface, - a second main surface, and - an edge surface of the optical element, the method of manufacturing the optical element involving the following steps: - during a first step of the method, the optical element is formed to give the optical element its final three-dimensional shape in terms of the first main surface, the second main surface and the edge surface of the optical element, - during a second step of the method, at least one of the surfaces of the optical element is cleaned, - during a third step of the method, a functional coating is applied to the first main surface and/or the second main surface.
