Abstract

In order to mitigate the risks of development of the M4 adaptive mirror for the E-ELT, CILAS has proposed to build a demonstration prototype and breadboards dedicated to this project. The objectives of the demonstration prototype concern the manufacturing issues such as mass assembly, integration, control and polishing but also the check the global dynamical and thermal behaviour of the mirror. The local behaviour of the mirror (polishing quality, influence function, print through...) is studied through a breadboard that can be considered as a piece of the final mirror. We propose in this paper to present our breadboard strategy, to define and present our mock-up and to comment the main results and lessons learned.
