The QF1 also features capacitive sensor feedback and is designed for demanding scanning applications, microscopy, or other optical application requiring high precision and throughput. The QF1 is 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. The QF1 has been designed to provide excellent geometric performance (straightness and angular errors) for critical microscopy and optics positioning applications. The QF1 has a closed-loop feedback option using a capacitive sensor design for sub-nanometer resolution and strong linearity. The capacitive sensors also measure the output of the positioning carriage directly, enabling superior accuracy and repeatability. When coupled with Aerotech’s Q-series controllers and drives, the QF1 demonstrates sub-nanometer positioning resolution and in-position stability. The QF1 is also available with threaded adapters to fit most microscopes and objectives and is available with a clear aperture of up to 29 mm.
