Inquiry (采购产品): Magnesium Flouride A/R coating Does your organizaton have the resources and facilities to apply a magnesium flouride A/R coating to a 203mm (8") correcting plate lens used in a Schmidt-Cassegrain relecting telescope? This correcting plate lens is optically undamaged although the present condition of its existing A/R coating has deteriorated over the years since the lens was first obtained in 1982. Deterioration of the A/R coating appears to have been caused by moisture condensation/evaporation during "thermal excursions" of the telescope when used in conditions of high humidity. **** Hidden Message ***** David F Leech 6229 S. 73rd East Ave Tulsa, OK 74133-1126 USA Company: Manucripts, Inc.
