Diamond-like carbon coatings to protect the optical surfaces of orbital telescopes from the outer space factors

The paper presents the results of experimental studies on the hardening of re­flecting surfaces of telescopes mirrors for space applications by applying dia­mond like coatings (DLC) to their surface with an electric arc method with laser burning of a carbon plasma and separation of the cloud of plasma. Describes the features of the technological process. Determines the relationship of the struc­ture and composition of the DLC layers to the physical and mechanical proper­ties of optical surfaces shows the promise of this technology for solving the problem of the effect of cosmic factors on the data surface. © 2020, Univelt Inc.
