Aerotech’s QFOCUS QF-46 offers closed-loop travels of 100 μm and 250 μm, and open-loop travels of 120 μm and 300 μm.
Aerotech’s QFOCUS QF-46 piezo nanopositioning stage series enables 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. The QF-46 offers larger and heavier higher numerical aperture (NA) objectives due to its higher inherent stiffness. QFOCUS QF-46 is guided by precision flexures that are optimized using finite element analysis to ensure high-stiffness and long device life. QF-46 piezo stages have the option of closed-loop feedback (-C) using a unique capacitive sensor design that results in sub-nanometer resolution and high linearity. QFOCUS QF-46 is available with threaded adapters to fit most microscopes and objectives. The microscope turret mounting allows easy and fast 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.
