Why Do We Need To Have AR Coating On The Glass?2023-03-31 15:15:41

AR (anti-reflective) coating on glass is used to reduce the amount of reflection from the surface of the glass. This coating allows more light to pass through the glass, rather than being reflected away, which results in increased clarity and image contrast.

Without an AR coating, glass can reflect up to 8% of incident light, which can be problematic in many applications, including eyeglasses, camera lenses, and architectural glass. This can result in a loss of visual acuity, lower contrast, and increased glare, which can all reduce the overall quality of the image.

AR coatings are made up of multiple thin layers of materials that have different refractive indices. The layers are carefully designed so that the reflection of light from each layer is out of phase with the reflection from the other layers. This results in a significant reduction in the overall amount of reflection from the surface of the glass.

Overall, AR coatings are an essential component of many types of glass, and they can greatly enhance the visual quality and performance of many different products.
