抗污膜可将多孔的减反射膜层覆盖起来
抗污膜的材料以氟化物为主,有二种加工方法,一种是浸泡法,一种是真空镀膜,而最常见的方法是真空镀膜。而最常用的方法是真空镀膜。当减反射膜层完成后,可使用蒸发工艺将氟化物镀于反射膜上。抗污膜可将多孔的减反射膜层覆盖起来,并且能够将水和油与镜片的接触面积减少,使油和水滴不易粘附于镜片表面,因此也称为 防水膜。
The antifouling film is mainly made of fluoride. There are two processing methods, one is immersion method, the other is vacuum coating, and the most common method is vacuum coating. The most commonly used method is vacuum coating. After the antireflection coating is completed, the fluoride can be plated on the reflective coating by evaporation process. Antifouling film can cover the porous antireflection film and reduce the contact area of water and oil with the lens, so that the oil and water droplets are not easy to adhere to the surface of the lens, so it is also called waterproof film.
