Nanometre-level performance in a compact, high-stiffness package

Aerotech

Aerotech’s QNP™-series of piezo nanopositioning stages offers nanometre-level performance in a compact, high-stiffness package. A variety of travel (100µm to 600µm) and feedback options make this the ideal solution for applications ranging from microscopy to optics alignment.

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

High Quality in a Compact Package
The QNP piezo stages are guided by precision flexures that are optimised 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 minimising 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-nanometre 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-nanometre 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.
