1. What is AR Coating? AR coating : anti-reflection coating The use of the substrate mirror plated reflective coating to interfere with the progress of light, to reduce the reflectivity and increase the transmittance. 2. How to test AR coating effect? The optical or quartz monitoring method is used to control the refractive index and thickness of medicinal materials, and the transmittance and reflectance are measured by using a spectrophotometer to meet the spectral data set by the product. 3. Application of AR Coating AR Coating is suitable for substrates such as glass, PC, PMMA, etc. AR products are widely used in mobile phones and digital product panels, camera lenses, flat panel display panels, and windows that require increased penetration. Here is the pic of the AR coating. AR Film AR Coating is based on the PCAP. Like a layer of oil. While different from A-R film. AR film is a polarizer added on the TFT LCD surface. Here is some introduction about AR film:
