Allen [12] Researched the floor roughness evolution of ion-beam polishing fused silica, and the outcome confirmed which the area roughness value enhanced with an increase in the removal depth. At the same time, experiments have also demonstrated that ion-beam sputtering can correctly decrease surface roughness [13,14].
