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. […]

Accelerated EDM Microstructuring Aided by Electroceramic Transducers

Piezoelectric high-speed motion improves performance of die-sinking EDM in the micron realm. The basic principle of the machining process, now known as electrical discharge machining (EDM), or die sinking, was discovered in the 1940’s by accident, when Russian scientists were trying to prevent the erosion of electrical contacts caused by sparking. Today, EDM is well […]

Piezo Flexure Actuators, Nanopositioners, and Other Piezo Mechanisms for Precision Motion Control Applications

Flexure-guided and motion-amplified actuators and positioning stages provide convenience and performance for the OEM designer and scientist. Piezo actuators, a special form of electro-ceramics, are the gold standard when it comes to precision, speed, and force in a small package. To make them more accessible for the OEM designer, manufacturers package the actuators inside an […]
