Mersen delivers a key part of the ELT, ESO’s future giant telescope

Mersen has announced the delivery by its subsidiary Mersen Boostec of the Reference Structure of the Adaptive Mirror of the ESO’s ELT (Extremely Large Telescope) to the Italian consortium AdOptica. 

In order to deliver to the astronomers an image corrected for the effects of the turbulence in the atmosphere and the vibrations of its huge structure, the ELT is equipped with an adaptive system. Combined with the fifth mirror (itself being manufactured by Mersen Boostec), the fourth mirror (M4) forms the core of what promises to be by far the largest Adaptive Mirror ever built.
