ESO Signs Contracts for the ELT's Gigantic Primary Mirror

(PresseBox) (Garching bei München, )
Contracts for the manufacture of the 39-metre primary mirror of ESO’s Extremely Large Telescope (ELT) were signed today at a ceremony at ESO’s Headquarters near Munich. The German company SCHOTT will produce the blanks of the mirror segments, and the French company Safran Reosc will polish, mount and test the segments. The contract to polish the mirror blanks is the second-largest contract for the ELT construction and the third-largest contract ESO has ever awarded.

The unique optical system of ESO’s Extremely Large Telescope consists of five mirrors, each of which represents its own significant engineering challenge.
