JENA, Germany, May 31, 2012 — Piezosystem jena has redesigned its PX 100 CAP piezoelectric nanopositioning stage. The travel range has been extended to 100 μm of motion in closed-loop mode without compromising the stage’s accuracy. For positioning control, a high-resolution capacitive feedback sensor has been built in. The sensor measures a deviation of the accuracy with subnanometer accuracy and operates in a direct metrology fashion. Another benefit of the redesign is the height, which has been reduced by 9 mm, so the stage now has outside dimensions of only 40 × 40 × 20 mm. It is appropriate for high-precision positioning of small components, such as mirrors or other optical components. Its high accuracy provides long-term stability under changing conditions.
