Lens coating

In order to obtain some new excellent properties, single-layer or multi-layer optical films with a certain thickness were plated on the lens by physical and chemical methods.

Strengthening film: also known as hard film, it is a layer of metal oxide mixed coupling agent with refractive index similar to that of lens. It has the characteristics of high hardness, high adhesion and high light transmittance. , can effectively improve the wear resistance of the lens, is not easy to peel off and yellow, and greatly prolongs the service life of the lens.

Anti-reflection film: Also called anti-reflection film, it uses the interference principle of light to interfere with the light reflected from both sides of the film, thus canceling each other, reducing or eliminating the light reflection of the lens, thus improving the transparency of the lens. Generally speaking, it is difficult to achieve ideal antireflection effect by using single-layer antireflection film, because single-layer antireflection film can only reduce the reflection of light in a certain band, while double-layer, three-layer or even more antireflection films are often used to improve the antireflection effect of visible light in all bands, thus making the lens more transparent.

Durable top film: also known as hydrophobic and oleophobic film, commonly known as waterproof film, is formed by evaporating and depositing hydrophobic substances such as fluoride on the lens surface. The hydrophobic material and dense film surface reduce the contact area between water/oil and the lens, which makes it difficult for water/oil to adhere to the lens surface, ensures the visual effect of the lens and is easier to clean.

Anti-static film: Indium tin oxide (ITO) is generally used to coat a thin film on the lens surface, which has good conductivity and transparency. ITO film can effectively eliminate static electricity accumulated on the lens surface and reduce dust adsorption on the lens surface.
