Ceramic ring INVR series

aluminacylindrical

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: Ultra-high vacuum compatibility (10^-8 to 10^-9 mbar.l/s) Good dielectric strength (13KV/mm in AC and 42KV/mm in DC) Four ceramic rings are used in one image intensifier tube. 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 field distribution: Supporting components such as photocathodes, MCPs, and phosphorescent screens; Maintain vacuum packaging and mechanical stability. Applications: - Head-mounted night vision - Spectrometers - Medical imaging device - Surveillance cameras Innovacera are specialized in metallized ceramics for more than 13 years. Our advantages: - Existing samples for testing - Rich experience in metallized ceramics - Customised solutions. - Material: High purity alumina ceramics (95-96% alumina) - Metallization: Mo/Mn metallized with Nickel plating - Shape: Custom, mostly ring - Color: White - Big ring size: OD30.5*ID24.2*3.20mm - Small ring size: OD30.5*ID27.5*1.06mm - Ultra-high vacuum compatibility: 10^-8 to 10^-9 mbar.l/s - Dielectric strength: 13KV/mm (AC), 42KV/mm (DC) - Applications: Night vision, spectrometers, medical imaging, surveillance cameras - Custom sizes and metallisation patterns available
