International audience; Adaptive optics is challenging for smaller telescopes (0.5∼2m) due to the small isoplanatic angle, small subperatures and high correction speeds needed at visible wavelengths, requiring bright stars for guiding and thus seve

An Adaptive secondary mirror (ASM) allows for the integration of adaptive optics (AO) into the telescope itself. Adaptive secondary mirrors, based on hybrid variable reluctance (HVR) actuator technology, developed by TNO, provide a promising path to
