Aerotech has introduced the QNP-Z series of piezo nanopositioning stages. The QNP-Z series provides the resolution, linearity, repeatability and high dynamics required for demanding applications ranging from microscopy to optics alignment.

QNP-Z piezo stages are guided by precision flexures that are optimised using finite element analysis. The resulting design offers excellent stiffness and resonant frequency (up to 1,050Hz), enabling high process throughput and fast closed-loop response. The stages have been designed to provide excellent geometric performance (straightness and angular errors) while minimising the overall stage package size.

All QNP piezo stages offer optional closed-loop feedback using a capacitive sensor for sub-nanometre resolution and high linearity. The capacitive sensors measure the output of the positioning carriage directly, enabling good accuracy and repeatability.

When coupled with Aerotech’s Q-series controllers and drives, QNP piezo stages demonstrate sub-nanometre positioning resolution and in-position stability (jitter), as well as high-positioning bandwidth. Software options such as Aerotech’s Dynamic Controls Toolbox and Motion Designer packages provide a range of advanced tools such as Learning Control, Harmonic Cancellation and Command Shaping, providing improved tracking errors and faster step-and-settle times.
