Description
Quartz Chamber for Ion Source ø17cm A37-0018-3
Quartz Glass for Plasma Source Vacuum Coating
High-purity gas-smelting fused silica glass, as its Si02 content is more than 99.99%, extremely high purity, colorless and transparent, less bubbles and impurities, high ultraviolet and visible light transmittance, and its thermal and chemical properties are excellent, are widely used as coating material, used for mirror multilayer coating and anti-reflective coating, etc.
We can produce, process and supply various shapes and specifications of quartz glass materials for coating in granular, sheet, ring, spherical, cylindrical, etc. At the same time, we also produce and supply related quartz glass parts and components for vacuum coating machine equipment.
