Zerodur lightweight blank

ZERODUR Schott, low thermal expansion glass-ceramic, is the material of choice for a wide variety of high-tech applications. From performing significant roles in navigation systems to improving the performance of microchips, Zerodur Schott, continually evolves with each challenge. MG-Optics acquires the outstanding process techniques in producing Custom Lightweight Blank, which can not only be machined based on the specific drawings, but also do the lightweight design with a maximum size of 1500mm. 

Material Properties

ZERODUR Schott, is used for Telescope Mirror Blank in monolithic and segmented telescopes. As well as low thermal expansion (any fluctuation in temperature due to environmental changes would obfuscate telescope images), the easy machinability and polishing properties of ZERODUR Schott, make it ideal for adaptive optics. And it was used to produce the 40 m segmented primary mirror in the Extremely Large Telescope (ELT) in Chile.

MG-Optics provide the processing Zerodur into complex geometries based on technical drawings and specifications from our customers. Our application and process engineers support you during the design phase of your product to get the most out of the zerodur properties for your individual application.

5-axis DMG 210P grinding machines allow for precision fabrication of zerodur up to 2000mm in diameter. The highlight of processing techniques is its light-weighting by grinding challenging aspect ratios with strict weight requirements.

By single-side and double-side polishing, we offer different surface-quality grades for dimensions up to 2000 mm. Depending on the size of your part, a roughness down to the um range can be achieved, and even further, MG-Optics will provide polishing process as your specifications. Zerodur lightweight blank, Zerodur Aspheric Mirror and Zerodur flat are our highlight products for your choice.
