Positioning stage offers nanometre precision at high speeds

23 January 2016

Aerotech’s QFOCUS QF1 piezo nanopositioning stage offers microscope objective and optics positioning with nanometre-level precision at high speeds.

The QFOCUS QF1 is guided by precision flexures that ensure high stiffness and long device life. The resulting design enables high process throughput and fast closed-loop response. The QF1 also provides excellent geometric performance (straightness and angular errors) for critical microscopy and optics positioning applications.

The QF1 has the option of closed-loop feedback using a novel capacitive sensor design for sub-nanometre resolution and high linearity. The capacitive sensors measure the output of the positioning carriage directly for high accuracy and repeatability.

When coupled with Aerotech’s Q-series controllers and drives, the QF1 provides sub-nanometre positioning resolution and high positioning bandwidth. Aerotech’s Dynamic Controls Toolbox and Motion Designer software packages provide 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.

The QFOCUS QF1 is available with threaded adapters to fit most microscopes and objectives.
