Abstract

On the basis of its experience gained on the VLT and GEMINI primary mirrors polishing REOSC will present his first comments on the preliminary technical specifications of some concepts (OWL, MAXAT) discussed with their instigators (ESO, AURA). Similarities with other projects presently running (CEA LIL) at REOSC that lead to consider such type of giant telescope with some unsuspected serenity. In addition the discussion will be illustrated with the REOSC experience in medium and large size off axis aspheric optics fabrication, the most recent being the Gran Telescopio Canaries project for which REOSC has just been awarded by GRANTECAN S.A. for polishing the 36 segments of this 11-m instrument.
