Abstract
The present invention relates to a method of manufacture (S) of an optical surface (4) of an optical part (1), comprising the following steps: obtaining (S1) an optical part (1) comprising a substrate (3) made of a first aluminium alloy and a coating (2) made of a second aluminium alloy having a porosity less than that of the first aluminium alloy; determining (S3) a reference shape defect and a reference surface roughness of the optical surface (4); determining (S4) polishing parameters for obtaining the reference surface roughness; depending on the polishing parameters, machining (S5) the coating (2) so as to give it a modified shape defect; and polishing (S6) the coating (2) according to the polishing parameters until the reference surface roughness and the reference shape defect are obtained.
