PITTSBURGH, Aug. 15, 2014 — Ensuring a long lifespan, the QNP-L series of linear piezo nanopositioning stages from Aerotech offers intense resonant frequency for high-process-throughput and fast closed-loop response.

Highly precise, frictionless flexure guidance achieves high stiffness while featuring finite element analysis. The devices offer closed-loop feedback using a capacitive sensor design that yields subnanometer positioning resolution and high-positioning accuracy. The capacitive sensors directly measure the output of the positioning carriage, enabling linearity to 0.0007 percent and superior positioning repeatability when compared to indirect feedback metrology techniques.

A variety of travel and feedback options make the stages ideal for applications ranging from microscopy to optics alignment.
