Allen [twelve] studied the area roughness evolution of ion-beam polishing fused silica, and the effects showed which the surface roughness benefit enhanced with a rise in the removal depth. Simultaneously, experiments have also revealed that ion-beam sputtering can effectively reduce surface area roughness [thirteen,fourteen].
