PI (Physik Instrumente) L.P. a leading manufacturer of nanopositioning and piezo-based precision motion-control equipment for nanotechnology, photonics and semiconductor applications, offers a new 3-axis nanopositioning / scanning stage, dubbed P-733.3CD. These high-resolution stages are designed for nanomanipulation, high resolution microscopy, imaging applications and materials research. The parallel-kinematics design (only one common moving platform for XYZ) reduces the moved mass, and enables -- together with the stiff design--higher operating speeds than other piezo scanning stages.

About P-733.3CD Nanopositioning Scanning Stages
P-733 are fast and highly accurate XYZ nanopositioning and scanning stages. These piezo systems provide a positioning and scanning range of 100x100x10µm together with sub-nanometer precision. The large clear aperture is an advantage in transmitted-light applications. The high-speed Z-axis (sub-millisecond response time) can actively compensate out-of-plane, Z-axis deviation during XY scans.
Capacitive Nano Measuring Sensors Provide Higher Linearity
Capacitive nano-measuring sensors read the platform position directly and without physical contact. This makes them free of friction and hysteresis, and allows very high levels of linearity, up to 99.99% with resolution to 0.1 nanometers. The Parallel Metrology configuration measures all axes against the same fixed reference, providing better precision than serial (individual) metrology.
Parallel Kinematics for High Trajectory Fidelity
In a parallel kinematics multiaxis system, all actuators act directly on the same moving platform. This means symmetrical dynamic properties of the X and Y axes, a prerequisite for fast, high-linearity scanning.
