The preparations for the design and construction of the Extremely Large Telescope (ELT) are in full swing. One of the most critical components of this enormous telescope is its segmented primary mirror (M1), for which TNO, in collaboration with VDL, has designed the mechanical segment support in the period 2015-2016. The dynamic performance of the structure has been validated experimentally.
