| Introduction Optical and functional coatings are used to enhance the performance of a component in various aspects of properties. For example, and uncoated polymeric lens reflects about 8% of incident light at each surface. To reduce the reflection to less than 1%, anti-reflection dielectric coatings can be applied on the lens surface via Physical Vapor Deposition (PVD). For optical components that transparent in nature but require reflective mirror surfaces, dielectric or metallic coating can also be applied to provide highly reflective surfaces. Other properties such as anti-finger-print, anti-dust, anti-fogging and hard protective layers are also parts of the coating application.
The performance of a coating depends on the number of layers, their thickness, the refractive index difference between them, and the material of each layer such as oxides, metals, or rare earth metals.
