Zerodur Glass

Zerodur glass is a composite material composed of crystalline phases in a glass matrix. This structure combines the characteristics of ceramics and glass,

Its characteristics are extremely low thermal expansion and high dimensional stability. In the temperature range of 0 to 50 ° C, the typical CTE is about 0 ± 0.007 × 10 ^ -6/° C. This means that it undergoes minimal size changes with temperature fluctuations, making it highly stable. The unique combination of low thermal expansion, high stability, and optical quality of zerodur glass makes it a valuable material in fields where accuracy and stability are crucial
