Excellent Performance

  • Optical Performance:Good transparency across the full spectrum. When there are strict requirements for the transmittance of ultraviolet and infrared rays, quartz glass is the preferred choice.
  • Thermal Performance:Quartz glass has a lower linear expansion coefficient than any other material, and it can even achieve zero expansion after doping treatment; quartz glass has excellent thermal shock resistance, it will not shatter when heated to 1000°C and then placed in water at 18°C.
  • Chemical Performance:Acid-resistant, quartz glass does not react with any acid other than hydrofluoric acid (HF) and will not be corroded by acids.
  • Electrical Performance:Low dielectric loss, suitable for the transmission of high-frequency electromagnetic waves (radio frequency, microwave).

spectrum of quartz glass

Quartz glass has high light transmission across the full spectrum and is suitable for applications that require special transmittance rates for ultraviolet (UV) and infrared (IR).
