Abstract The present work is devoted to the study of the intensification of the physicochemical processes of purification and the modes of processing of metal optics. The main theories of solubility are analyzed, the relationship of optical parameters with the energy characteristics of detergent medium in the process of physicochemical cleaning is revealed. A model of the physicochemical process of cleaning metal optics is proposed. To test it, an installation, implementing a model of the physicochemical process of removing contaminants from the surface of mirrors, was developed. It worked in a semi-automatic mode in a closed technological cycle with an automated system for monitoring the chemical purity of the optical surface both before and after cleaning, and during the process. © 2022 The Authors.
