Black Coatings for Vacuum Use



2001

I am looking for a black coating to be used inside vacuum vessels of astronomical CCD cameras to prevent stray light of the incoming light beam on thermally conductive shields. We are currently using a black coating also recommended by the NASA outgassing list, but with larger and larger areas to be covered by the black coating we would like to improve the outgassing situation. The typical pressure of the vacuum vessel is in the range of 10-7 to 10 -6 mBar.

You should consider Black Oxide. Black oxide has great advantages over coatings in this type of atmosphere. Good Luck.
