14 Aug 2007 March 2007 - PI (Physik Instrumente) L.P., a leading manufacturer of nanopositioning and piezo-based precision motion-control equipment introduces a new ultra-high-resolution positioning & scanning system. The minute P-363 PicoCube®, together with its ultra-low noise E-536 driver / controller, provide significantly higher resolution and positional stability than previous multi-axis scanning stages.
More information on the controller and a graph showing resolution data is available here:

- Parallel Metrology for Better Multi-Axis Accuracy
- Small & Rugged Design with Titanium Case
- Vacuum Compatible
Typical Applications: AFM (Atomic Force Microscopy), SPM (Scanning Probe Microscopy) and Nanomanipulation, Bio-Technology, Nanotechnology, Nano-Imprint, Semiconductor & Data-Storage Test Equipment.
Why are PicoCube® Systems Superior?
PicoCube® systems were designed to overcome the limitations of open-loop piezo-tube based scanners which provide high resolution motion but poor linearity and trajectory guidance.
The compact PicoCube® is based on exceptionally robust, high-stiffness piezo drives rather than tubes and employs non-contact, direct-measuring, parallel-metrology capacitive sensors for position feedback. The low-inertia drives allow for a resonant frequency of 10 kHz, important for high speed scanning applications.
Why Parallel Metrology?
Parallel metrology can “see” all controlled degrees of freedom simultaneously and compensate for off-axis motion in real time. The benefits are a reduction of runout and off-axis errors, straighter multi-axis motion and improved repeatability.
Controller
The new ultra-low-noise E-536 closed-loop controller provides unprecedented positional stability and can be controlled with analog or digital signals. LabView Drivers are available.
