  Circular Sapphire Windows
  Sapphire Windows are normally flat polished round transparent optical windows suitable for the applications of extreme conditions, such as high-pressure, vacuum and corrosive atmospheres.
  Sapphire windows are required to withstand harsh environmental conditions and provide high levels  of performance and reliability.
  Our super sapphire windows polishing processes enable us to polish precision sapphire windows with diameter up to 200mm, surface accuracy up to 0.1 lambda (lambda 633 nm) and surface quality up to 10/5 MIL.
  UltiTech also offers coatings and metallization solution for sapphire windows. Metallization enables sapphire windows to be hermetically brazed into a metal housing for harsh or vacuum applications.
