After the competitive Phase B design, we completed an advanced preliminary design (Phase 1 study) in early 2015. This study comprehended the development, construction and test of an advanced Demonstration Prototype that has been fully tested, both for dynamic and optical performances, demonstrating that the concept developed in the preliminary design was fulfilling the strict M4 specifications. The control bricks embedded in the prototype were already at pre-production level.
In June 2015 the AdOptica consortium between Microgate and ADS International has signed the contract for the Final Design, Manufacturing, Delivery and On-Site Integration of the M4 Adaptive Unit of the E-ELT. The activity will cover all activities until delivery and system re-integration and test in Chile, planned for June 2023.
