ELT secondary mirror during transport to annealing facility

The ELT secondary mirror blank, cast out of ZERODUR®, arrives at the SCHOTT 4-metre blank annealing facility in Mainz, Germany in May 2017. Here, it will go through a slow cool-down, machining and heat treatment sequence over the next year. It will then be ready to be ground to precisely the right shape and polished.
