PIEZOCONCEPT is the leading provider of nanopositioners dedicated to applications such as Super Resolution Microscopy, Optical Trapping and Atomic Force Microscopy. Our customers include many leading scientists engaged in leading edge research at world class universities and institutes. For almost a decade, researchers bought stages equipped with capacitive sensor. But our users wanted better stability and linearity and new powerful microscopy techniques demanded a major rethink. Something more stable was required. We decided to take a long hard look at these systems and see if there was a better, more elegant, solution to providing accurate and stable positionning. We developed a range of ultra-stable nanopositionner able to meet a wide range of microscopy applications with significant advantages over the currently available nanopositionners. As one of our biggest advantages, the sensor we use outperforms high-end capacitive sensor because of their exceptionally high signal, leading to picometric stability. Also, because of the very low-noise electronics and the flexure design stage we offer, we can ensure subnanometric (or sub-nanoradian) noise floor.
