Circular Sapphire Windows

for Optical , Medical equipment, and Analytical instruments applications
circular sapphire windows
  • 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

    • Circular sapphire windows are characterized by their exceptional hardness, strength, and resistance to wear. Sapphire optical windows demonstrate remarkable resilience against harsh abrasives like sand and particulate matter, ensuring minimal impact on clarity. This particular feature positions sapphire crystal windows as the preferred choice for a variety of applications, including aerospace windows, vision systems for downhole drilling, inspection windows, watch crystals, and gun sights.

    AOG boasts extensive experience in producing customized sapphire windows, providing options with C plane (C Axis), R plane (R Axis), and A plane (A Axis) cutting. Through our advanced sapphire window polishing processes, we achieve high-precision optical flatness, a surface finish with minimal scatter, and the elimination of surface and subsurface damage.
