Schott Zerodur CTE

Schott Zerodur ® has always been known for its extremely low coefficient of thermal expansion (cte), which can remain stable under temperature changes. This means that Zerodur glass will not change with temperature fluctuations within the temperature range of 0 ± 0.007 × 10 ^ -6/° C. This is an ideal material for high-precision and stable applications, which is crucial for engineering in astronomical telescopes and precision measuring instruments
