Abstract

The purpose of this paper is to make an overview of the development status of anti-reflective coating in optical coating. The preparation process of anti-reflective coating mainly includes the selection of coating materials and the design of the coating system based on the application requirements, and then the selection of appropriate preparation process for the preparation of the coating.Therefore, this paper first describes the principle of anti-reflective coating, then describes the design methods of single-layer and multilayer membrane systems, and compares the optical transmittance of the two methods in visible bands.Secondly, it describes the four kinds of coating preparation technology commonly used nowadays, including vacuum evaporation method, chemical vapor deposition method, sol-gel method, sputtering method, and its main application fields and advantages and disadvantages are summarized.Then the anti-reflection coating materials commonly used in coating technology and the film structures which are constantly updated and developed to adapt to different application fields are described.Finally, two applications of anti-reflective coating nowadays are listed, including multi-layer special optical coating applied by the space detection camera developed by our group and the application of the anti-reflective coating in solar cells.
