Specification for Optical Sapphire WindowSapphire is a single crystal aluminum oxide (Al2O3). It is one of the hardest materials. Sapphire has good transmission characteristics over the visible, and near IR spectrum. It exhibits high mechanical strength, chemical resistance, thermal conductivity and thermal stability. It is often used as window materials in specific field such as space technology where scratch or high temperature resistance is required -Sapphire glass are ideal for applications where high pressure, high temperature, high thermal loads, vacuum, scratch resistance, corrosion resistance, small coefficient of friction as well as optical and insulating properties are a consideration.-Sapphire windows normally need to work under extreme operating conditions, so hard AR coating is required to withstand harsh environmental conditions and improve resistance to scratching.-Sapphire substrate has a high refractive index, thus usually requires an antireflection coating on sapphire windows for sufficient transmission in the region of interest. -In some applications where sapphire windows need to be soldered or bonded to metal.Product NameProfessional custom Optical Grade Saphire Observation Window Round Sapphire Glass Window 0.5-200mm IR Optical Sapphire WindowMaterialsSynthetic sapphire crystalDimeterDia0.4mm to 230mm, customize availableLength0.05mm to 150mm, customize availableTolerance0.01mm for Diameter and +/-0.1mm for length, customize availableSurface QualityS/D80/50~S/D10/5Flatness1/4 lambda per inch @633nm, 1/8 lambda per inch @633nmChamferCommon bevel,Fine ground or polishedCoatingaccording to customer's requirement2. Properties of Optical Sapphire WindowOptical Windows are used as viewports to protect other components within an optical assembly, instrument, or laser. In certain applications, optical windows are required to withstand harsh environmental conditions and provide high levels of performance and reliability. Sapphire window has several unique properties that make it the ideal material for these applications.1. Synthetic Sapphire, the single crystal form of Al2O3, is one of the hardest materials ( 9 Mohs hardness). Because of its structural strength, the sapphire window can be made much thinner than other common optical windows, with better transmittance performance.2. High thermal stability and excellent thermal conductivity make the sapphire window suitable for the applications in high power. The loss in a sapphire window is less than in another common optical window.3. Sapphire windows can withstand considerably higher temperatures than most optical windows with zero degradation.4. Sapphire Windows will not get dark and lose their brilliancy when exposed to UV light.5. Sapphire windows are extremely stable and resistant to attack by strong acid due to sapphire's high dielectric constant.6. Sapphire windows offer wideband transmission from UV to Mid-IR (0.15-5.5μm).All these unique properties make sapphire windows the ideal material for extreme mechanical, chemical & optical applications. 3. Feature of Optical Sapphire Window-Transmits Wavelengths Ranging From UV to Mid-Infrared-Extreme Surface Hardness Chemical Resistance-Thinner and Stronger than Standard Glass Windows-High thermal conductivity -High bulk damage threshold4.Fields of Application for the Optical Sapphire Window-Scanner-Watch glasses-Semiconductor applications (e.g. wafers)-Cell phones (displays and display protection)-Infrared-/ and UV-applications (e.g. sensors, monitoring systems, thermal cameras)-Medical devices (e.g. endoscope windows, scalpels and laser surgery, light guides in dermatology)Military applications (e.g. night vision devices and cameras, satellite and space technology, control systems)
