Abstract:

Surfaces of mirrors or other optical devices employed in satellite programs will in time become contaminated with thin layers of polymer films. These films originate most likely from outgassing and polymerization by u.v. radiation with condensation on critical optical surfaces. The contaminant films degrade the reflectivity of mirrors and the performance of critical optical surfaces. Atomic oxygen from a high-frequency plasma restores optical surfaces to their original properties by rapid non-contaminating, non-destructive oxidation of the polymer film. Author
