  • Publication number: 20200270745
    Abstract: A magnetron sputtering scanning method for manufacturing a silicon carbide optical reflector surface modification layer and improving surface profile includes (1) for a silicon carbide plane mirror to be modified, first utilizing diamond micro-powders to grind and roughly polish an aspherical silicon carbide reflector with a conventional polishing or CCOS numerical control machining method; (2) after the surface profile precision of the silicon carbide reflector satisfies a modification requirement, utilizing a strip-shaped magnetron sputtering source to deposit a compact silicon modification layer on the surface of the silicon carbide reflector; (3) then, utilizing a circular sputtering source to modify and improve the surface profile of the reflector; and (4) finally, finely polishing the modification layer, and achieving the requirements for machining the surface profile and roughness of the reflector.

  • Patent number: 10359621
    Abstract: A frost-prevention film system of a large-aperture reflecting optic infrared telescope used in an extremely low temperature environment and a preparation method thereof is disclosed. The frost-prevention film system has the following structure: a transparent conducting film layer, an intermediate insulation layer, a reflecting film layer and an outermost medium protection layer in sequence from a main telescope mirror surface, wherein both sides of the transparent conducting film layer are provided with conducting electrodes. The steps are as follows: (1) a preparation step; (2) a step of plating a conducting film; (3) a step of plating an intermediate insulation layer; (4) a step of plating a reflecting film layer; (5) a step of plating an outermost medium protection layer; and (6) a step of plating conducting electrodes.
