The Technique of Ion Beam Etching Polishing

Article Preview

Abstract:

The accelerated gas ions collide with the surface material, the atom or molecule on material surface is removed by momentum transferring. Depositing a layer low viscosity of the thin film materials on the original surface of the optical, such materials will form a layer thin film on the surface of optical element that is lower than the original. Remove the high-spatial frequencies and obtain super precision optical surface.
