Home | Sapphire Optics Specifications Contact Us  Links Sapphire Optics   As a leading supplier of sapphire optics, Red Optronics supply a wide variety of custom sapphire optics, include windows, lens, prisms for a wide range of applications. Our monthly output of conventional sapphire products exceed 10K pcs a month.  We also supply simple and complex optics or optical assemblies for prototype and small production volumes. 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  Transmission Curve: 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.
