Custom Zerodur Advantages

Zerodur has been a key material in applications ranging from laser gyroscopes to large astronomical telescopes. Its high-performance characteristics are comparable to Corning’s ULE glass, featuring a near-zero thermal expansion coefficient and exceptional stability against temperature variations. Custom Zerodur glass, precisely machined, can be used in various high-precision instruments and optical devices. Additionally, multiple CTE grades (from Level 2 expansion to ultra-zero expansion) make it suitable for a wide range of engineering applications.
