Sapphire (single crystal aluminum oxide) is a material commonly used in optical, electronic and chemical applications due to its material properties. Create a new folder below. Translations are not retained in our system. Top. 48 kv/mm, (1.2kv/mil), Virtually unaffected by any solvents or acids at room temperature. You will have access to both the presentation and article (if available). Sapphire is slightly birefringent, general purpose IR windows are usually cut in a random way from crystal but for specific applications where the birefringence is an issue, an orientation is selected. Characterization of AFB sapphire single crystal composites for infrared window... Journal of Micro-Nanolithography, MEMS, and MOEMS. © 2020 guild optical Associates. (Some etching by hot phosphoric acid and strong caustics at temperatures exceeding 600°C – 800°C) Thermal Properties: Melting Point: ~2053°C (3727°F) Proceedings Volume 7056, Photonic Fiber and Crystal Devices: Advances in Materials and Innovations in Device Applications II; Advancements in MWIR window materials and structures. Sapphire is one of the strongest and hardest materials available; it has excellent abrasion resistance and exceptional thermal shock properties. Sapphire is the material of choice for stringent optical applications involving exposure to high stresses and harsh environments. Usually this is with the optic axis at 90 degrees to the surface plane and is known as "zero degree" material. Sapphire optical components outperform and outlast their fused silica and quartz counterparts within sapphire’s transmission range of 190nm to 5000nm. Optical Transmission of UV Grade Sapphire and Standard Extreme hardness and high mechanical strength (withstands intense environmental conditions) Excellent thermal conductivity/heat resistance. Commercial Grade, Sapphire optical transmission for 1mm thick windows, Mechanical, Thermal and Electrical To access this item, please sign in to your personal account. Sapphire Properties Chemical Properties: Non-porous, unlike alumina ceramics; Unaffected by weathering; Unaffected by hydration; Virtually unaffected by any solvents or acids at room temperature. Sapphire (single-crystal aluminum oxide Al 2 0 3 ) has desirable optical properties in that it can transmit wavelengths from 150 to 6000nm and because the strength of Sapphire when thinned is useful at wavelengths close to their transmission limits. Title: Microsoft Word - Sapphire Optical Properties.doc Author: One Created Date: 2/28/2007 4:54:35 PM This will count as one of your downloads. Nonreciprocal terahertz optical phenomena with spins and plasma waves (Conference... Hydrogen effect on the properties of sapphire, An Investigation Of Epr Spectra In Ti-Doped Sapphire. Your use of this feature and the translations is subject to all use restrictions contained in the Terms and Conditions of Use of the SPIE website. Sapphire is resistant to attack by strong acids, enabling use in a corrosive atmosphere. Because of the remarkable hardness of sapphires – 9 on the Mohs scale (the third hardest mineral, after diamond at 10 and moissanite at 9.5) – sapphires are also used in some non-ornamental applications, such as infrared optical components, high-durability windows, wristwatch crystals and movement bearings, and very thin electronic wafers, which are used as the insulating substrates of special-purpose solid-state electronics … Site by Delta Marketing Group. You currently do not have any folders to save your paper to! NOTE: These sapphire properties may be dependent upon relative crystal orientation, form and surface quality.
