Zerodur Lightweight Mirrors
Zerodur substrates are renowned for their exceptional thermal stability, ensuring minimal deformation even under extreme temperature fluctuations. This stability translates to unparalleled optical performance by minimizing image distortion.
Yudi Optics leverages the excellent processing characteristics of Zerodur to offer customized solutions, allowing for the precise control of tight tolerances and the creation of complex geometric components. Our expertise in ultra-lightweight processing makes Zerodur an ideal choice for large optical systems, including large-aperture astronomical telescopes.
Why Zerodur for Lightweight Mirrors
Zerodur is an optical ceramic manufactured by SCHOTT known for its near-zero coefficient of thermal expansion of ±0.10 x 10-6/°C, an order of magnitude lower than most glass types. Optical mirrors made from ZERODUR® have an extremely low coefficient of thermal expansion, making this glass-ceramic material ideal for applications where the optical mirrors are exposed to fluctuating and/or very low temperatures. It is one of the leading materials for advanced aerospace applications, as its CTE properties and low helium leakage rate make it the material of choice for many close tolerance optical and space applications.
