Ion Beam Figuring for the Center for Advanced Optical Systems (CSOA)
An Ion Beam Figuring machine allows a contactless polishing process. A small beam of positive ions (Argon) is projected against a substrate surface. Ions produce a chain collision with the atoms that allows material to be extracted in a controlled way. Before g to carry out the process, the surface must be measured with an interferometer, which
