Sapphire Window with Holes for aerospace, medical, and industrial applications
  • Extremely hard, strong and wear resistant
  • Excellent thermal conductivity/heat resistance
  • Exceptionalchemical stability
  • Excellent transmission bandwidths (UV to IR)
  • Blank substrates, AR-coated pieces, and precision windows are available
  • The sapphire optical wedge window has similar function with traditional optical window. It also has two well-polished planes, and the two planes form a angle. Sapphire wedge can be used as isolating components. In addition to features similar to normal wedge windows, the sapphire wedge window has a harder, stronger, and more wear-resistant properties. It is widely used in some special environments.

    Sapphire windows with hole are frequently used in aircraft equipment and sensors due to their exceptional durability and corrosion resistance, as well as their great temperature resistance and extremely wide spectrum transmission range.

  • Anti-reflection coatings are also available at your specified wavelength.
  • Sapphire transmits ultraviolet light, but sometimes exhibit fluorescence when subjected to powerful ultraviolet sources. For this reason, they are best suited for use with visible to infrared wavelengths.
  • Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
