Glass tubes, initially metallized with thin layers of chromium and copper, were electroplated with copper and black chrome. The optical properties of the black-chrome-plated tubes were excellent with ..cap alpha../sub s/ approx. = 0.94 and epsilon/sub TH/ (25/sup 0/C) approx. = 0.08. Thermal-cycling tests of the tubes revealed relatively stable optical properties until temperatures around 400/sup 0/C in vacuum were reached.
