Allen [twelve] researched the area roughness evolution of ion-beam sharpening fused silica, and the results showed which the surface roughness price improved with an increase in the elimination depth. At the same time, experiments have also proven that ion-beam sputtering can correctly decrease surface area roughness [thirteen,14].
