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.
They feature high speed, millisecond responsiveness, are vacuum compatible and nonmagnetic.
High-speed actuators and zero-wear flexure designs are also available.
medical and pharmaceutical applications include: precision motion control, optics and imaging, fast valve control, applications in high magnetic fields, vacuum, liquid dispensing, fast pumps, scanning microscopy, OCT and MRI.
PI offers three advanced types of ceramic, nonmagnetic linear motor actuators that can replace classical actuators.
The three types are distinguished by force, travel range and speed and precision.
For short travel ranges (up to 0.5mm) with high forces and very rapid response (submillisecond feasible) PiezoMove Flexure Actuators are recommended.
Alternatively, theoretically unlimited travel ranges are provided by both the PILine and Nexact linear motor actuators.
Whereas the faster motor actuators (PILine) provide speeds up to 800mm/s, the Nexact type motor actuators feature higher resolution and forces.
In contrast to servo or stepper motor actuators, the piezo ceramic linear motors effect linear motion directly, without the need to transform rotation with gears and leadscrews.
Backlash and wear are eliminated and the drive is maintenance-free.
Piezo ceramic actuators exhibit high stiffness and are self-locking when powered down with nanometre position stability, and zero heat dissipation or servo-dither at rest. Request a free brochure from PI (Physik Instrumente) ...
