PITTSBURGH, Feb. 2, 2016 — Aerotech Inc. has announced the QFocus QF1 single-axis, microscope objective, piezo nanopositioning stage, offering optics positioning with μm-level precision at high speeds. The stage is guided by precision flexures that are optimized using finite element analysis to ensure high stiffness and a long device life. Closed-loop feedback uses a unique capacitive sensor design that allows for sub-nm resolution and high linearity. The capacitive sensors measure the output of the positioning carriage directly. The QFocus QF1 is available with threaded adapters to fit most microscopes and objectives. The microscope turret mounting allows for easy and fast positioning at the desired orientation, with a clear aperture of up to 29 mm. An ultraprecise capacitive sensor feedback option and high structural stiffness are available for demanding scanning applications, microscopy, or any optical application requiring high precision and throughput.
