Low expansion glass-ceramic is produced through precise control of the ratio between the crystalline and glass phases. Its core characteristic lies in a near-zero thermal expansion coefficient across a broad temperature range, coupled with exceptional uniformity, high strength and high hardness, which makes it an ideal choice in extreme harsh environment. It is widely used in ultra precision fields such as the blanks of large astronomical telescopes, resonator cavities of laser gyroscopes, spacecraft window materials, optical platforms of photolithography machines and precision instrument bases.
Radiation Shielding/ Resistant Glass
Radiation shielding/ resistant glass can weaken and shield X-ray, γ ray, neutron ray and space high-energy particles, and is widely used in medical protection, nuclear industry protection and space shielding.
Near-infrared filter glass can provide reliable protection for the sensitive electronic and optical components on the back of the lidar window, and withstand harsh environments. Its core feature is that it has high transmittance for the near-infrared 905nm and 1550nm wavebands, and extremely low transmittance for the ultraviolet and visible wavebands. It can effectively filter the stray light at non laser application wavelengths, improve the signal-to-noise ratio of the system, and significantly enhance the 3D scanning ability of the lidar. It is mainly used in the field of automotive and lidar protective windows.
High-strength glass can withstand high-temperature and high-pressure environments, with a softening temperature exceeding 900 °C. It possesses high mechanical strength, excellent thermal shock resistance, and high-temperature deformation resistance, while maintaining exceptional chemical stability and thermal stability even in high-temperature environments.It is mainly used in aerospace, petroleum exploration, natural gas exploration, chemical and other fields.
