XYZ-Piezo-Scanner for AFM Provides 25 Picometers Resolution
Friday, March 30, 2007

PI (Physik Instrumente) L.P., a leading manufacturer of nanopositioning and piezo-based precision motion-control equipment for bio-nanotechnology, photonics and semiconductor applications offers 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.
Features & Advantages: --High-Speed XYZ Scanner for AFM / SPM & Manipulation Tool for Nanotechnology --Custom, High-Stiffness Shear Piezo Drives Provide up to 10 kHz Resonant Frequency for Faster Response and Higher Scanning Performance --Ultra-Low-Noise Controller Enables 25 Picometers (0.025 nm) Resolution --Capacitive Feedback for Exceptional Precision and Linearity --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. Extensive software support including LabView™ drivers is provided.
