March 23, 2016 - Aerotech introduced QNP-Z Z-axis piezo nanopositioning stages for extreme precision research and industrial requirements. 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 are available. They are guided by precision flexures that are optimized 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 geometric performance (straightness and angular errors) while minimizing overall package size. Available adapter plates allow linear, XY, and Z-axis stages to be mounted together for simultaneous multi-axis positioning.
