What are the differences between magnetron sputtering AR coating and ordinary AR film?

A: AR film, also known as Anti-Reflection film, works on the principle of reducing reflectivity by utilizing the destructive interference of light. However, the effects vary significantly depending on different processing techniques. Process type Reflectance (approximately) Process characteristics: Ordinary screen glass 4.0% No AR coating solution immersion process 3.0% Low cost, limited effect, may decay over time electron beam evaporation process 2.0% Mid-range process, medium effect Guanfudun magnetron sputtering process ≤ 0.5% nano-scale inorganic molecule deposition in vacuum environment The film layer is dense and uniform, and the effect is long-lasting and stable. Woowhead Guanfudun adopts vacuum magnetron sputtering AR· anti-glare coating, with a reflectivity of ≤ 0.5% (self-test data under the brand's laboratory standard test environment), which is about one-eighth of that of ordinary screen glass. It can significantly improve visibility under both indoor lighting and outdoor sunlight.
