Round Sapphire Windows

for Aerospace, Medical equipment, and Sapphire flash lamps applications
round sapphire windows
  • High strength, high hardness, high temperature resistance
  • Abrasion resistance, corrosion resistance
  • Maximum diameter 600mm
  • Good light transmission performance (150 ~ 5500 nm)
  • Excellent electrical insulation performance, and good mechanical properties

    • Round sapphire windows are the optimal choice for applications involving high pressure, vacuum conditions, or corrosive atmospheres. In challenging environments, these windows outperform all other optical materials, establishing a superior barrier against the elements. When faced with harsh conditions, round sapphire windows become essential for delivering elevated levels of performance and reliability.

    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.
