  • Sapphire Viewport Transmission Curve
    Sapphire is a synthetic, hexagonal single crystal anisotropic material which displays substantially different physical, thermal, dielectric and optical characteristics when measured along different axes. MDC sapphire viewports are constructed using 90° crystal orientation, where the crystal
  • Hermetic Sealing of Sapphire Windows
    The use of sapphire material for optical sensing, emitting or detecting has been increasing considerably in the last 20 years, hence the term "window". Sapphire offers a high-quality optical surface finish, the hardness to prevent scratches, and high temperature processing capabilities. Although
  • Sapphire Luminescence - F Centers
    On the basis of an extensive study of the optical behavior of neutron-bombarded crystalline sapphire we proposed that oxygen vacancies with one electron (F centers) and two electrons (F centers) are responsible for the 4.8 and 6.1 eV absorption bands, respectively. This defect model has been
  • Optical Properties of Single-Crystal Sapphire Fibers
    Single-crystal sapphire fibers have been grown with the laser-heated pedestal-growth method with losses as low as 0.3 dB/m at 2.94 um. With the incorporation of a computer-controlled feedback system, fibers have been grown with less than 60.5% diameter variation, or 1.5 um for a 300-um fiber
  • Computer Power User Article - Sapphire ATI Radeon 9600 XT
    Sapphire ATI Radeon 9600 XT 2004 CPU Special Issue Page(s) 92 in print issue Add To My Personal Library Sapphire ATI Radeon 9600 XT To call Sapphire's ATI Radeon 9600 XT reliable is not to say that it is also boring. Although it's true that the package leaves us without any mouthwatering goodies
  • Computer Power User Article - Sapphire Radeon X800 GTO2
    hear about Extreme Edition processors or Platinum Edition graphics cards. Dreamy as that stuff may be, it's just too expensive. Enter Sapphire s Radeon X800 GTO
  • Computer Power User Article - The Sapphire Radeon X800 GTO2 Mod
    unused pipelines and wring more performance from some X800 GTs. They were right, and we will show you how it is done. You can easily unlock the unused pixel pipelines on some X800 GT-based cards from PowerColor, Connect3D, and Sapphire by flashing the BIOS on the card. There are some things to watch
  • Optical Absorption in Sapphire
    Optical absorption over a large dynamic range obtained by two different experimental techniques is reported for an un-doped alpha alumina single crystal. Absorption data are presented in two energy ranges: 0.94-3.5 eV and 4.5-8.6 eV. Vacuum ultraviolet (VUV) absorption measurements were performed on
