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.
