Allen [twelve] examined the surface area roughness evolution of ion-beam polishing fused silica, and the final results confirmed that the floor roughness price improved with a rise in the removing depth. At the same time, experiments have also demonstrated that ion-beam sputtering can successfully lower area roughness [thirteen,14].
