With massive growth of various technology-driven businesses, particularly in aerospace and electronics industries, need for related optical components also surged. One such industry that emerged as a result of this quick rapid industrialization is the optical coatings industry. Optical coatings were produced as thin-film multilayers of various materials using specific deposition techniques and are applied to optical components that are employed at wavelengths between UV and far-IR. These coatings are deposited as thin-film multilayers using a range of materials and deposition techniques. The most basic kind of coating is made by layering metals such as silver, gold, and aluminum. Many cutting-edge applications make use of optical coatings to increase transmission while reducing reflection. In addition, these coatings are utilized on a wide range of consumer products and research optical instruments because of their versatility. https://www.emergenresearch.com/industry-report/optical-coating-market
