Metallised Ceramic Rings for Image Intensifier Tubes(IIT)
Innovacera’s metallised ceramic rings are used in image intensifier tubes for night vision equipment and other instruments. Specifications: -High purity alumina ceramics-95-96% alumina. -Metallization-Mo/Mn metallized with Nickel plating. -Customised sizes and metallisation patterns available. Features: Shape As per request. Mostly are using ring shape Size Big ring OD30.5*ID24.2*3.20mm Small ring OD30.5*ID27.5*1.06mm Or custom by your drawing Color White Properties l Ultra-high vacuum compatibility (10 -8 to 10 -9 mbar.l/s) l Good dielectric strength (13KV/mm in AC and 42KV/mm in DC) Four ceramic rings are using in one image intensifier tubes. Each metalized ceramic ring serves not only as a part of the electrode conductive path, but also as a mechanical positioning and vacuum holding function. The rings are often precisely bonded through brazing or metal support structures to form a cylindrical main structure. Functional: Realize electrode cascade and electric fi...
