European Southern Observatory (ESO) | Largest tip-tilt mirror in the world | ELT Updates @ESOobservatory | Uploaded 4 months ago | Updated 9 hours ago
M5, the fifth mirror on the light path of ESO’s Extremely Large Telescope (ELT), has reached an important milestone: its blank, the shaped piece of material that is later polished to become the mirror, has just been finalised.
It might look small compared to the ELT’s enormous 39-metre primary mirror, but in reality, it is the largest tip-tilt mirror in the world. It will move 10 times per second without bending. Together with M4 — a flexible and very fast deformable mirror — they will both correct atmospheric turbulence and telescope vibrations, delivering sharp images.
