Direct Piezo Drive for Ultra-Fast Scanning and Positioning
The P-725.xDD microscope objective positioners were designed for extremely fast motion. Their ultra-stiff direct piezo drive (1.2 kHz resonant frequency) enables the highest scanning rates and response times of only 5 msecs - essential for time-critical tasks.

Superior Accuracy with Direct-Metrology Capacitive Nano-Measuring Sensors
Capacitive position feedback with sub-nanometer resolution is used. PI's proprietary capacitive sensors measure position directly and without physical contact. They are free of friction and hysteresis, a fact which, in combination with the positioning resolution of well under 1 nm, makes it possible to achieve very high levels of linearity. A further advantage of direct metrology with capacitive sensors is the high phase fidelity and the high bandwidth of up to 10 kHz.

Alternatively compact, more cost-efficient strain gauge sensors (SGS) featuring nanometer resolution are implemented. Absolute-measuring SGS-sensors are applied to appropriate places on the drive train and thus measure the displacement of the moving part of the stage relative to the base.
