Nanometer accurate shaping with fluid jet polishing

This article describes the Fluid Jet Polishing process. An overview of the theoretical dependence of various important parameters is given. We discuss some results obtained with FJP, including typical material removal rates and roughness values. Some recent experiments are described that show that it is also possible to obtain removal rates as small as one nanometer per minute for glass surfaces. Specific surface profiles are created, both with and without the use of surface protecting masks.
