Abstract
A hard optical film, a method for producing the same and use thereof. The film is an optical film with a nano-dual-phase structure, and features a regulable thickness, high visible light transmittance and hardness, a flat and uniform surface, and a great application prospect. The hard optical film is prepared on a surface of a substrate by magnetron sputtering, having high binding force between the obtained film and the substrate, such that the substrate has a very high hardness, a very strong abrasion resistance and certain corrosion resistance.
