Long range for PZT steering mirror
Polytec PI, NanoPositioning Group, has released what it claims to be the world's longest-range high-speed PZT-driven two-axis mirror scanner.
Stages go a long way accurately
Polytec describes Hera as the world's longest-travel precision-guided PZT nanopositioning stages for advanced applications such as mask alignment, inspection and metrology.
The parallel-kinematics design (only one common moving platform for x-y-z) reduces the moved mass, and enables higher operating speeds than other piezo scanning stages.
Typical Applications include scanning microscopy, nanomanipulation, metrology/interferometry, biotechnology, semiconductor testing, mask/wafer positioning, and image enhancement/stabilisation.
These piezo systems provide a positioning and scanning range of 100x100x10um together with sub-nanometer precision.
The large clear aperture is an advantage in transmitted-light applications.
The high-speed z-axis can actively compensate out-of-plane, z-axis deviation during x-y scans.
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 0.1nm.
The parallel metrology configuration measures all axes against the same fixed reference, providing better precision than serial (individual) metrology.
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. Request a free brochure from PI (Physik Instrumente) ...
