Adaptive Optics – the Next Generation. 11,000 Actuators to Aid Search for Exoplanets with the E-ELT

PI and Fraunhofer IOF Cooperate on New Large Scale Adaptive Optics Project   Piezo-driven active mirrors (tip/tilt motion) and adaptive mirrors (multiple actuators deforming the mirror surface) have been employed in most high-end astronomical telescopes for more than two decades. The resolution gain compared to passive mirrors is typically more than one order of magnitude. […]

Ultra-Stable Mirror Mounts for LINC-NIRVANA High Resolution Imager are based on Self-clamping PiezoWalk Motors

An extremely stable motorized mount for initial alignment of two dichroic beam splitters in the instrument was required. The mirrors reflect visible light and transmit the NIR are located close to the pupil plane are very sensitive to tilt and flexure errors which could be introduced to the wave-front sensor. The technical specifications to be […]
