“…Between 2008 and 2010, two contracts with Microgate/ADS/SAGEM and Cilas/AMOS were run in parallel with the objective to provide a preliminary design for the 42 meter telescope E-ELT. The two contracts have provided two different designs in term of technology [4], [5] and performance. End of 2010, the E-ELT design baseline was finalized selecting the Microgate/ADS/SAGEM design.…”

“…These fully adaptive ELTs offer many advantages including good LGS re-imaging and high throughput [46]. However given the risk of placing several DMs in the main telescope, the reliability of DMs will be a major concern [14,25]. Assuming that the reliability issue is resolved, we consider two families of designs based on two-mirror basic configurations: Ritchey-Chrétien and aplanatic Gregorian systems.…”

“…The first group features very large DMs (4-m diameter), which can be made only as segmented mirrors with current technology [14,25], yet they can be fully integrated into the main telescope design. The additional complexity made by introducing several segmented DMs in the telescope prohibits their direct use for current projects, however, novel phasing sensors might overcome difficulties with phasing segmented DMs [26].…”

“…This telescope has a novel 5 mirror design [2] [3] including the adaptive mirror in the telescope, explaining its exceptional size. CILAS has proposed, in partnership with AMOS, BOOSTEC, ONERA, Observatoire de Paris Meudon a concept based on piezostack technology [4] that fulfills all the requirements (no show stopper identified).…”
