High Precision Z-axis Nanopositioners Added to Piezo Nanopositioner Family

Aerotech has introduced a series of Z-axis piezo nanopositioning stages for extreme precision research and industrial requirements. The new QNP-Z stages join a family that includes the QNP-L linear and QNP-XY stages, providing a complete range of positioning solutions for most extreme precision applications.

They provide the resolution, linearity, repeatability, and high dynamics required for the most demanding applications from microscopy to optics alignment. Nanometer-level precision is assured by resolution to 0.15 nm, linearity to 0.007%, and bidirectional repeatability to 1 nm.

A variety of travels (100 μm to 600 μm), feedback options, and vacuum versions add to the versatility of this stage series. They are guided by precision flexures that are optimised using finite element analysis. The resulting design offers outstanding stiffness and resonant frequency (up to 1050 Hz) enabling high process throughput and fast closed-loop response.

All QNP stages provide excellent geometric performance (straightness and angular errors) while minimising overall package size. Available adapter plates allow linear, XY, and Z-axis stages to be mounted together for simultaneous multi-axis positioning.
