Abstract

In 2017, the European Southern Observatory (ESO) awarded a contract for the Polishing, integration and final figuring of the Segment Assemblies of the primary mirror (M1) for the Extremely Large Telescope (ELT) to Safran Reosc. Since then, the design and commissioning of a production unit dedicated for ELT M1 has been accomplished and the plant have been producing many mirrors since spring 2022. We present the status of the project, some lessons learned and highlight the successes that have been achieved so far.
