Abstract (en)
[origin: WO2020225225A1] The present invention relates to a method for smoothing surfaces (12), with which method surfaces (12) can be smoothed more effectively than before and can also be smoothed in a direct machining method. Above all, surfaces (12) of metal optics, particularly aluminium-based optics (10) can be smoothed more effectively than before. The optical properties (refractive index and coefficient of absorption) of surfaces (24) smoothed in such a way remain substantially unchanged. Furthermore, the smoothed surfaces (24) have a high long-term stability with regard to their chemical and/or mechanical resistance and their geometric and/or optical properties.
