The Extremely Large Telescope (ELT), currently under construction in Chile by the European Southern Observatory (ESO), will soon become the largest telescope in the world.
It will be distinguished by its main mirror, 39 metres in diameter and made up of 800 segments, which will be phased and controlled by the Phasing Diagnostic Station (PDS) instrument.
Bertin Winlight will supply all the transport optics for the PDS, which will feed the various optica diagnostics. This involves the custom manufacture of 59 high-precision lenses, once again demonstrating the expertise of our teams in complex optical systems.
The ELT will enable major advances in astronomy, particularly in the study of exoplanets, dark matter, and the first galaxies.
