A revolutionary precision polishing method called magnetorheological finishing (MRF) has been developed to overcome many of the fundamental limitations of traditional polishing techniques. MRF is a deterministic subaperture process that has a demonstrated ability to finish spherical and plano surfaces to an accuracy of better than 30nm peak to valley and surface microroughness less than 1 nm on optical glasses, single crystals, and glass ceramics.
