ZERODUR®
Low-thermal-expansion even in harsh environments
The inorganic, non-porous lithium aluminum silicon oxide glass-ceramic, ZERODUR® is characterized by its extremely low-thermal-expansion, which is homogeneous throughout the entire volume. Additionally, it possesses a very low rate of imperfections, high strength compared to other glass-ceramics and is transparent to visible light. Smooth surfaces with a roughness in the sub-nm range are also achievable.
