Optical coatings are widely used to change the reflectivity of the lens surface, from glasses to high-power laser applications. The core technology of femtosecond laser coating is that its coating has the characteristics of low dispersion and high damage threshold. This article talks about three commonly used sputter coating techniques, and introduces the physical principles...Continue Reading

What is PVD Coating Technology? Physical Vapor Deposition (PVD) is a thin film preparation technique that physically vaporizes the surface of a material source (solid or liquid) into gaseous atoms, molecules, or partially ionized into ions under vacuum conditions. Then, a film having a specific function is deposited on the surface of the substrate by...Continue Reading
