Related Product Features:
  • High-purity silicon dioxide (SiO₂ ≥ 99.99%) ensures exceptional physicochemical stability.
  • Dimensions of 35.04mm diameter and 2.95mm thickness balance mechanical rigidity and frequency stability.
  • Piezoelectric effect enables use in resonators and filters for communication devices.
  • High transmittance (>85% visible light, excellent UV range 185-250 nm) for optical detection and laser systems.
  • High-temperature resistance up to 1,100°C long-term and 1,450°C short-term.
  • Low thermal expansion coefficient (~5.5×10⁻⁷/°C) ensures stability in high-temperature environments.
  • Chemical stability resistant to strong acids (except hydrofluoric acid), outperforming ceramics and metals.
  • Large diameter minimizes edge effects and enhances optical uniformity for precision instruments.
Faqs:
  • What is the maximum temperature resistance of high-purity fused silica glass windows?
    Short-term resistance up to 1,450°C, long-term operational temperature up to 1,100°C, with a low thermal expansion coefficient of 5.5×10⁻⁷/°C, making it ideal for high-temperature environments.
  • What is its role in laser systems?
    Serves as laser cavity mirrors or fiber-optic connectors, providing low insertion loss (e.g., SC/APC interfaces) and minimizing thermal stress-induced scattering.
  • What industries benefit from fused quartz windows?
    Industries such as semiconductors, optoelectronics, medical devices, communications, and scientific instruments benefit from their high transmittance, thermal resistance, and chemical stability.
