ZERODUR® glass-ceramic has been one of SCHOTT's most unique and extraordinary products for over 50 years. With an extremely low-thermal-expansion, it's essential for a large number of demanding high-tech applications requiring exceptional precision.
Highly accurate under extreme conditions
The extremely low-thermal-expansion of ZERODUR® is homogenous throughout the entire bulk volume, which makes it ideal for a large range of applications involving precise positioning or imaging under changing temperature conditions.
Impressive machinability from small to large
Thanks to its extraordinary machining properties, ZERODUR® can be manufactured in a variety of sizes and shapes, from tiny prisms to meter-sized mirror blanks. High degree light-weighting and surfaces optimized for bending strength are key areas of SCHOTT's expertise, which makes ZERODUR® ideal for space applications.
Product variants
ZERODUR® is suitable for many high-tech applications, ZERODUR® TAILORED offers the best material for individual temperature requirements, and ZERODUR® K20 is suitable for your high-temperature applications.
