The study of HfO2 and SiO2 optical thin films sputtered by multi-targets RF magnetron sputtering system in this thesis. We can see 300 nm ~ 400 nm the change on the optical properties including transmittance、refractive index and extinction coefficient along with mirco correction on structure and surface roughness at different vacuum pressure. We can get optical thin films of better optical properties. Base on this,we sputtered single-side and double-side high transmittance anti-refractive coating for the application on UV optic technique.
