A method of manufacturing an optical component comprising a substrate made of a fusible material, said method comprising the following steps a) and b) or steps a), b) and c) or steps a), b), c) and d): a. Trueing the optical component to form at least one optical surface on said substrate; b. Smooth grinding said optical surface of the optical component so as to obtain a smoothed optical surface; c. Polishing said smoothed optical surface so as to obtain a polished optical surface; d. Finishing said polished optical surface so as to obtain a finished optical surface; characterized in that said method comprises, after any one of steps b) and/or c), the following steps: e. Inspecting (30', 50', 70') the smoothed or polished optical surface of the optical component to detect and locate at least one surface defect to be eliminated on the smoothed or polished optical surface of the optical component; f. For each surface defect to be eliminated located at step e), applying a laser beam (35, 55, 75) over an area encompassing said surface defect to be eliminated, said laser beam having a laser emission wavelength liable to be absorbed by said material, so as to produce a local remelting of the fusible material, the power density of the laser beam and the duration of application of the laser beam being function of the transverse dimensions of the surface defect to be eliminated, so as to form, in place of the surface defect to be eliminated, an area of laser remelted material; g. Continuing the method of manufacturing the optical component at step c) when step f) has been performed before the end of step c); or, respectively, at step d) when step f) has been performed after the end of step c). a. Trueing the optical component to form at least one optical surface on said substrate; b. Smooth grinding said optical surface of the optical component so as to obtain a smoothed optical surface; c. Polishing said smoothed optical surface so as to obtain a polished optical surface; d.
