Aerotech QFOCUS QF-46Z Single-Axis, Microscope Objective, Piezo Nanopositioning Stage

Enable microscope objective and optics positioning at high-speeds with nanometre-level performance

Aerotech

Aerotech's QFOCUS® QF46Z piezo nanopositioning stage series enables microscope objective and optics positioning at high-speeds with nanometre-level performance. Available in closed-loop travels of 100µm and 250µm (120µm and 300µm open-loop), the QF46Z provides long travels without sacrificing dynamic operation and nanometre precision.

 

Features:

  • Travels from 100µm to 300µm
  • High-stiffness and dynamics resulting in outstanding step-and-settle and scanning performance
  • High-precision, frictionless flexure guidance
  • Long device lifetime
  • Superior positioning resolution and linearity with direct-metrology capacitive sensor option
  • Mounting flexibility with a variety of threaded adapters or mounting holes for custom mounting arrangements
  • Clear aperture to 29 mm diameter

The QF46Z is designed with next-generation optical instruments and laser machines in mind. For example, the QF46Z can perform better than competitive offerings with larger and heavier higher numerical aperture (NA) objectives due to its higher inherent stiffness. The QF46Z is perfect for any demanding optical application requiring high precision and throughput with long travels.

 

Precision Mechanical Structure
The QFOCUS QF46Z 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.

In addition, the QF-46 has been designed to provide excellent geometric performance (straightness and angular errors) for critical microscopy and optics positioning applications.

High-Resolution and Positioning Accuracy
The QF-46 piezo stages have the option of closed-loop feedback (-C) using a unique capacitive sensor design that results in 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 QF46Z demonstrates sub-nanometre positioning resolution, 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. OEM drive options are also available.

 

Flexibility
The QFOCUS QF46Z is available with threaded adapters to fit most microscopes and objectives. The microscope turret mounting allows easy and fast positioning of the QF-46 at the desired orientation. In addition, tapped holes on the stage body provide alternative mounting for custom interfaces in machines or other optical instruments. The QF-46 is available with a clear aperture up to 29mm. Custom stage designs, travels, and threaded adapters are available.
