Allen [12] analyzed the surface roughness evolution of ion-beam sharpening fused silica, and the effects showed that the surface area roughness price greater with a rise in the removal depth. Simultaneously, experiments have also revealed that ion-beam sputtering can efficiently reduce surface area roughness [13,14].
