SCHOTT ZERODUR® is a preferred mirror substrate material for applications where the highest levels of thermal dimensional stability are needed. SCHOTT now offers ZERODUR®, a glass-ceramic optimized for minimal response to thermal perturbations, in monolithic 4-meter diameters in highly lightweighted forms, important for the larger mirrors used in space telescopes.More
APG-760 phosphate laser glass is made for high-performance applications at 1.05 μm. The glass is available in various versions and can be adapted for a variety of applications. Dielectric coatings are also possible.
The gigantic 39-meter primary mirror for the Extremely Large Telescope (ELT) will soon be made up of 798 ZERODUR® glass-ceramic components. SCHOTT is set to deliver a total of 949 mirror substrates made of ZERODUR® to the European Southern Observatory (ESO). Thanks to SCHOTT’s investment of more than $11 million, the company is well prepared to respond to the increased demand.More
