Thin films and coatings are a backbone for optical applications in industry, medical equipment, automotive, building and communication sectors, as well as in household and consumer products. Thin films applied on the substrate, such as glass or polymers, for example, polycarbonate, enable the substrate to gain beneficial functions which can improve its energy saving properties, optical transparency, and operational life span. This chapter focuses on the application of protective coatings on optical systems with an emphasis on the methods for characterizing and optimizing the coatings quality, in particular their mechanical and tribological performance, and environmental stability.
