Kick-off for Mirrors and Sensors for Biggest Eye on the Sky
ESO’s Extremely Large Telescope (ELT) moves forward with 4 contracts for important parts of its innovative 5-mirror optical system.
The casting of the largest ever secondary mirror — the largest convex mirror ever produced.
4.2 metres!
The casting of an unusual concave 3.8-m tertiary mirror.
Sophisticated support cells for the ELT’s secondary and tertiary mirrors.
4608 edge sensors to help the 798 segments of the ELT’s primary 39-metre mirror stay in the right place — most accurate sensors ever in a telescope.
ELT. Thinking Big. Aiming High.
