Infrared glass has good transmittance in the infrared band, which can transmit light without causing light reflection and scattering.
2. Thermal stability:
Infrared glass has stability at high temperatures and does not generate thermal stress or expansion, making it suitable for use in high-temperature environments.
3. Chemical stability:
The chemical properties of infrared glass are stable and will not be corroded by most chemical substances.
4. High mechanical strength:
Infrared glass has high strength and stiffness, and is not easily damaged or broken.
