The P-562.6CD 6-axis nanopositioning stage from PI (Physik Instrumente) is a unique piezo-driven, flexure-guided positioning system based on the parallel-kinematics principle. The system enables precision motion in all degrees of freedom with 1 nanometer and 100 nano-rad closed-loop resolution, respectively.
Travel ranges are 200 µm linear and rotational / tilt angles are 1 milliradian.
This piezo positioning system is equipped with direct-measuring capacitance sensors and a digital closed-loop controller provides up to 3 orders of magnitude better linearity / accuracy compared to conventional piezo flexure stages.
Applications include semiconductor manufacturing / testing, data-storage, nano-manufacturing, bio-technology, nanotechnology, super-resolution microscopy, nano-imprint lithography.
Solid-State Piezo Drive and Frictionless Guidance System:
P-562 piezo stages incorporate high stiffness, solid state piezo drives, frictionless flexure guiding systems and absolute measuring capacitance feedback sensors for closed-loop control. Due to the high stiffness of the piezo drives and the low inertia of the moving platform, the system can provide rapid step and settle performance with response times in the millisecond range.
The parallel-kinematics mechanical design is supported by a parallel direct-motion metrology sensor system. With parallel direct-metrology, all non-contact sensors monitor the moving platform in reference to the fixed frame. Off-axis and runout errors are eliminated by the motion controller in real-time.
