QNP50L-250 Single-Axis Linear Piezo Nanopositioning Stage
Description
Design Features
Travel ranges from 100 µm to 600 µm available
Long device lifetime
High-precision, frictionless flexure guidance system
Superior positioning resolution and linearity to 0.007% with direct-metrology capacitive sensor options
Mounting compatibility with other QNP-series piezo nanopositioners
Open-loop and vacuum versions
Aerotech’s QNP™-series of piezo nanopositioning stages offer sub-nanometer-level performance in a compact, high-stiffness package. A variety of travel (100 µm to 600 µm) and feedback options make this the ideal solution for applications ranging from microscopy to optics alignment.High Quality in a Compact Package
The QNP piezo stages are guided by precision flexures that are optimized using finite element analysis to ensure high-stiffness and long device life. The resulting design offers outstanding stiffness and resonant frequency enabling high process throughput and fast closed-loop response. Furthermore, these stages have been designed to provide excellent geometric performance (straightness and angular errors) while at the same time minimizing the overall stage package size.High-resolution and Positioning Accuracy
All of the QNP piezo stages have the option of closed-loop feedback using a unique capacitive sensor design that allows for sub-nanometer resolution and high linearity. The capacitive sensors measure the output of the positioning carriage directly enabling superior accuracy and repeatability.
Ultra-Precision Control
When coupled with Aerotech’s Q-series controllers and drives, the QNP piezo nanopositioning stages demonstrate sub-nanometer positioning resolution and in-position stability (jitter), and high-positioning bandwidth. Software options such as Aerotech’s Dynamic Controls Toolbox and Motion Designer packages provide a host of advanced yet easy-to-use 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 using 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.

Design Flexibility
Aerotech’s QNP piezo stages are available with capacitance sensor feedback or without feedback (open-loop). Open-loop provides a cost-effective option for applications where compact size, high-dynamics and sub-nanometer positioning resolution are required, but absolute positioning accuracy and repeatability are not required. Open-loop designs can also be used where the piezo position is controlled via an external feedback source (interferometer, vision system, photodetector, etc.).
An optional mounting plate provides direct mounting to English or metric breadboard optical tables. The QNP-series also includes XY and Z stages in which common travels mount together with adapter plates.
All QNP piezo stages are available in vacuum-prepared versions upon request.
