Sapphire WindowsFeatures: Excellent optical, physical and chemical properties. It has high hardness, high melting point, high transparency, high acids resistant.Applications: Micro electrics, photoelectron, aviation&aerospace instrument, laser system.Description:Crystal sapphire possesses a unique combination of excellent optical, physical and chemical properties it is the hardest of the oxide crystals. sapphire retains its strength at high temperatures, has good thermal properties, excellent transparency and chemically resistant to common acids. These properties encourage its wide use in hostile environments where optical transmission in the range from the visible to the near infrared is required.Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3) and is useful in a transmission range from 0.15 - 5.5μm.Specifications:?Material:?Sapphire?Dimension Tolerance:?+0.0, -0.1mmThickness Tolerance:?± 0.1mmSurface quality:?80/50Clear Aperture:?>85%Flatness:?λper 25mmParallelism:?3& acute;?Bevel:?<0.25mm X 45°Coating:?Upon requirement
