Paper Abstract

Because of the severe system requirements for the VLTI Auxiliary Telescopes (i.e. mass budget, mechanical stability, image quality and environment), the design and manufacturing of the Primary Mirror Unit required a big effort in FEM computations and a high technology manufacturing process for the primary mirror. Specific tools have been developed for the cell assembly and mirror integration. This paper describes the design and assembly techniques of the M1 unit. A review of the most important techniques used at AMOS for the manufacturing of the lightweighted primary mirror (1.87 m diameter, f#1.44) is described. Final test results of M1 unit are presented to demonstrate the compliance with the allocated sub-system requirements.
