“…This paper focusses on the performance analysis that has been performed during the critical design phase of the ASM development, with regard to the wavefront error performance, the dynamical performance, and the impact of an actuator failure. For more in-depth discussion about the mechanical design and MAI-status the reader is referred to [2], while [4] discusses the test-strategy and test-preparations for this ASM.…”

TNO and industrial partners are developing a new type of adaptive secondary mirrors (ASM) for the University of Hawaii 2.2-meter telescope, consisting of 210 actuators, in an overall volume of ø63cm by 15cm height, and having an aspherical convex mirror-shell of 3,5mm thickness. The novel actuator technology enables a compact system without active cooling that can be retro-fitted within the same mass and volume of an existing passive secondary mirror. This development enables affordable and reliable ASM systems for the world's larger telescopes as well as the many telescopes in the 2-4 meter class. This paper presents the overall design of this ASM and focusses on the performance analysis regarding its figure quality, its dynamical behavior and the related closed loop performances.
