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 highly reliable all-ceramic Nexline drives have won a technology award from the semiconductor community and are ideally suited for static and dynamic high-precision positioning of high loads.
PI currently offers three standard Nexline actuators (N-110, N-214, N-215) for closed- and open-loop operation with maximum loads up to 60kg.
The new E-755 Nexline motion controller combines sophisticated control algorithms, high-end 32bit digital filters and output drivers with extremely low-noise, 24bit D/A convertors.
In closed-loop operation, outstanding linearity, within 0.001% over the full travel range, is achieved by polynomial linearisation.
Nexline controllers can be run in closed-loop and open-loop mode.
They provide an input for the nanometre precision incremental linear encoders that are integrated in standard Nexline actuators.
Thanks to its low-noise 24bit D/A convertors, the E-755 controllers can provide picometre level resolution in the highly dynamic short-range/dithering mode that the actuators support.
The E-755 controllers come with an extensive software package including LabView drivers for simple and flexible automation of nanopositioning tasks. Request a free brochure from PI (Physik Instrumente) ...
