17 September 2012 Manufacturing optics of a 2.5m telescope
Author Affiliations +
Over the past few years, Sagem REOSC has designed, manufactured and tested a 2.5m ALT/AZ telescope and its complete observatory. The next stage - integration - should occur in 2012. The aim of this paper is to develop the different stages of the project from technical and management's point of view. The telescope is a 2.5m-class telescope with an aperture of F/8. It is composed of a 2.5m primary mirror made of Zerodur©, a silica secondary mirror and a rotating tertiary mirror that allows pointing at Nasmyth foci. In addition, a wide field corrector can be adapted either at Cassegrain focus or at Nasmyth focus. Results achieved on the realization of such optics will be presented. An emphasis on the concurrent engineering and the problem solving approach will also be presented.
