In this study an analysis of remediation strategies all based on in situ low-pressure RF plasma cleaning approaches is reported, including a quantitative determination of the optimum process parameters and their influence on the chemistry as well as the morphology of optical test surfaces. It appears that optimum results are obtained for a specific pressure range as well as for specific combinations of the plasma feedstock gases, the latter depending on the chemical aspects of the optical surfaces to be cleaned.<\/p>\n<p><a href=\"\/wp-content\/uploads\/2015\/06\/in-situ-plasma-mirror-cleaning-Journal-Article.pdf\" target=\"_blank\" rel=\"noopener\"><i class=\"fa
