SCHOTT to equip the main mirror of the world’s largest telescope with ZERODUR® glass-ceramic
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, including spares, made of ZERODUR® to the European Southern Observatory (ESO).
This artist's video takes the viewer into the dome of ESO's Extremely Large Telescope on Cerro Armazones in northern Chile. It reveals the complex and massive telescope structure and the 39-metre segmented main mirror. The final moments show night falling and the telescope starting work by switching on multiple lasers to create artificial stars high in the atmosphere.
