Low Expansion Glass-Ceramic
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.
