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 0.2 - 5.5µm
Synthetic Sapphire is a single crystal form of corundum, Al2O3, also known as alpha-alumina, alumina, and single crystal Al2O3. Sapphire is aluminium oxide in the purest form with no porosity or grain boundaries, making it theoretically dense. The combination of favourable chemical, electrical, mechanical, optical, surface, thermal, and durability properties make sapphire a preferred material for high performance system and component designs. For various semiconductor applications, sapphire is the best choice in comparison with other synthetic single-crystals.
Sapphire substrates / wafers: EPI-polished, optically polished, lapped or as-cut sapphire disks, windows, substrates, blanks as well as epitaxial structures “silicon-on-sapphire” (SOS) are described at the next page,

· Sapphire is used in analytical applications where combinations of high temperature, pressure, and hydrofluoric acid species are encountered. These applications need the survivability of sapphire, while often needing other properties such as favourable UV (ultraviolet) or IR (infrared) transmission.
· NMR (Nuclear Magnetic Resonance) tubes; Sapphire is used for very high-pressure applications in replacement of glass or quartz tubes.
· Sample preparation - sapphire is used in digestion cells as sheaths and liners. When hydrofluoric acid is used, sapphire replaces quartz components
· Analytical chemistry - for mass spectroscopy, ICAP, and other systems, sapphire replaces quartware to improve durability and reduce contamination while offering good UV transmission.
Medical applications:
· Sapphire is used in surgical systems for laser transmission and in contact with bodily fluids.
· Surgical tips - sapphire is used in contact tips for various surgical laser applications
· Endoscope lenses - sapphire is often used in endoscope lenses due to its durability in contact with tissues and in sterilisation environments such as autoclaving
· Sapphire knives - with a sapphire knife, thinner sections are possible. The near perfect cutting edge of this knife / blade gives distortion-free sections down to 10 microns thick.
Optical applications:
· Sapphire is used for short and long wavelength applications (UV and IR) beyond the range where conventional optics performs adequately. High temperatures and hostile environments also necessitate the use of sapphire optics.
· Illumination windows - for very high brightness illumination, sapphire windows survive the very high heat while providing the broadest spectral transmission.
