Aerotech introduces QFOCUS QF-46 piezo nanopositioning stage

July 27, 2016 - Aerotech’s QFOCUS™ QF-46 piezo nanopositioning stage series is designed to enable microscope objective and optics positioning at high-speeds with nanometer-level performance. It is available in closed-loop travels of 100 μm and 250 μm, and open-loop travels of 120 μm and 300 μm.

The QF-46 is designed with next-generation optical instruments and laser machines in mind. It is suitable for any demanding optical application requiring high precision and throughput with long travels.

QFOCUS QF-46 is guided by precision flexures that are optimized using finite element analysis. The resulting design offers stiffness and resonant frequency enabling process throughput and fast closed-loop response. In addition, the QF-46 has been designed to provide geometric performance (straightness and angular errors) for critical microscopy and optics positioning applications.

QF-46 piezo stages have the option of closed-loop feedback (-C) using a capacitive sensor design that results in sub-nanometer resolution and high linearity. The capacitive sensors measure the output of the positioning carriage directly, enabling accuracy and repeatability.

QFOCUS QF-46 is available with threaded adapters to fit most microscopes and objectives. The microscope turret mounting allows positioning at the desired orientation. 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 29 mm. Custom stage designs, travels, and threaded adapters are available.
