Abstract

Aiming at the development trend of the application of large-aperture optical remote sensors [1], the technical route of plating feasible and effective large-aperture optical element mirrors has been studied. Combining the technical characteristics of the physical vapor deposition of silver mirrors for large-aperture optical elements[2] and related risks, a new process method is proposed based on the relevant characteristics and specific requirements of silver mirrors. The principle of this method is the chemical silver mirror experimental reaction [3]. In this paper, by improving the concentration of the raw materials required for the silver mirror reaction in the laboratory, increasing the surface activity of the substrate, and adjusting the reaction environment, a method that meets the needs of specific production testing is explored. Aperture optical element silver film reflector plating method, and related tests on film firmness, film reflectivity and film surface shape, the test results are in line with the expected requirements, this article is a high-efficiency, high-efficiency large-aperture optical element the thin-film coating of silver-coated mirrors puts forward a new process route.
