Sapphire Window and other optical Windows. Sapphire Lens, Sapphire Optics and Sapphire Prism

Home | Sapphire Window Specifications Contact Us  Links Sapphire Window   Sapphire Sapphire 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. Physical Properties of Sapphire Crystal Symmetry Hexagonal System Lattice constant A a =4.75 ;  c =12.97 Transparence range μm 0.18- 4.5 Density g/cm3 3.98 Mohs hardness 9 Melting point oC 2030 Thermal conductivity W/m/K 0.04 Expansion coefficien 10-6/K 8.4 Refractive Index 1.0 μm 1.755   Sapphire Window Sapphire window is made from synthetic sapphire and can be made much thinner than BK7 windows..  It is highly durable with a wide transmission range. Sapphire window is best suited for scratch resistance application that requires better transmission over a wide range spectrum.   High Precision Sapphire Windows Material: Sapphire Clear Aperture: 85% Flatness: <l/4 Parallelism: <1 arc minute Surface Quality: 40/20 Bevel: 0.25mm x 45° Coating: Available upon request   Standard Sapphire Windows Material: Sapphire Clear Aperture: 85% Flatness: 1 l per 25mm @633nm Parallelism: <3~5 arc minutes Surface Quality: 60/40 Bevel: 0.25mm x 45° Coating: Available upon request   Standard Product Information High Precision Standard Precision Part No. f ± 0.1 (mm) T±0.2 (mm) Part No. f ± 0.1 (mm) T ± 0.2 (mm) WIN2201 10.0 6.0 WIN2101 10.0 3.0 WIN2202 25.0 6.0 WIN2102 15.0 3.0 WIN2203 50.0 10.0 WIN2103 25.0 3.0       WIN2104 50.0 3.0   Ordering Information for Standard Product: Part No, -Coating Wavelength For Example, WIN2101-1064   Ordering Information for None Standard Product: Note: custom size, wedge angles and coating are available upon request.
