QNP-L data sheet - .PDF file.

QNP-L series linear piezo nanopositioning stages from Aerotech give nanometre-level performance in a compact, high-stiffness package. A variety of travel and feedback options make the stages particularly suitable for applications such as microscopy and optics alignment.

The QNP-L linear piezo stages are guided by precision flexures optimised using finite-element analysis to ensure high stiffness and long life. The design is also said to provide excellent resonant frequency for high process throughput and fast closed-loop response, as well as unparalleled geometric performance.

All QNP-L piezo stages offer closed-loop feedback using a unique capacitive sensor design that yields sub-nanometre positioning resolution and high-positioning accuracy (linearity). The capacitive sensors directly measure the output of the positioning carriage, enabling superior linearity and positioning repeatability when compared with indirect feedback metrology techniques such as strain-gage feedback.

When coupled with Aerotech’s Q-series controllers and drives, QNP-L piezo nanopositioning stages demonstrate sub-nanometre positioning resolution and in-position stability (jitter), and high-positioning bandwidth. Aerotech’s Dynamic Controls Toolbox and Motion Designer software packages provide tools such as learning control, harmonic cancellation, and command shaping, providing improved tracking errors and faster step-and-settle times.

Automatic parameter and calibration identification is accomplished with Aerotech’s Flashconfig feature. The stage is automatically identified and all operational parameters including axis calibration data are uploaded into the controller ensuring safe, accurate, and true ‘plug-and-play’ operation.

Aerotech’s QNP-L piezo stages are available with capacitive sensor feedback or without feedback (open-loop). An optional mounting plate provides direct mounting to English or metric breadboard optical tables. Common travels of the X, XY, and Z stages mount together without adapter plates. All QNP piezo stages are available in vacuum-prepared versions upon request.
