square sapphire windows
  • High-hardness 9 Mohs, outstanding scratch resistance and chemical stability
  • Material: Optical grade single Sapphire crystal (Al2O3)
  • High transparent to wavelength of light between 0.3 μm (UV) and 5 μm (IR)
  • Widely used for high-temperature, chemical-resistant, and optical applications
  • Great transmittance, about 80%-90% in the visible light spectrum (approximately 400-700 nm)
  • Extremely high melting temperature (2030 °C)
  • Customized by design artwork

    • Due to sapphire's structural strength and superior transmission, rectangular sapphire optical windows can be made much thinner than other common optical windows, with better transmittance performance. AOG provide antireflective and dielectric coatings for sapphire windows and can guarantee thin film spectral uniformity over the clear aperture.

    Sapphire windows mainly contain four types: circular windows, oval windows, oblique circular windows and step windows.

    Notes

  • 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.
