Precision positioning stage works to
240mm/s
PCI-card-driven, high-speed voice coil positioning stages provide up to 20mm (0.8in) of travel and resolution to 100nm for precise motion control usage.
PI (Physik Instrumente), a leading manufacturer of nanopositioning and precision motion-control equipment for bio/nanotechnology, photonics, semiconductor and life science applications, offers the V-106 QuickScan series of PCI-card-driven, high-speed voice coil positioning stages, providing up to 20mm (0.8in) of travel and resolution to 100 nanometers * Applications - these closed-loop stages were designed for high-dynamics precision motion control applications, like those in biotechnology; laser beam control; scanning; optics and lens finishing; and fiber optics

Precision linear stages are at affordable price
For precision automation uses, a motorized family of high-precision linear stages are combined with low-cost servo motor controller to form very affordable motion control systems.
Closed-loop scanning stages are flexure-guided
Closed-loop flexure-guided piezoelectric scanning stages provide a record travel range of 1000 microns and allow nanotechnology/precision microscopy probing of larger areas than before.
* Cost-effective PCI-bus motion controller card with on-board amplifiers - QuickScan systems are driven by a PCI-bus motion controller card with on-board linear servo amplifiers.
Based on a frictionless, backlash-free, voice coil linear motor drive and a high-precision optical encoder featuring 100 nanometer resolution, the systems provide extremely smooth motion with velocities to 240mm/s (9.6in/s).
* Higher dynamics and lifetime than screw-type drive mechanisms - V-106 QuickScan stages achieve significantly higher dynamics than leadscrew-based units, with scanning frequencies to 20 Hz and above for small loads.

PCI-Bus piezo nanopositioning controller arrives
Believed to be the world's first PCI-bus digital nanopositioning controller for closed-loop piezoelectric positioners and scanners, it provide more flexibility and better overall value.
Another advantage of the frictionless voice coil drive is greater reliability and lifetime than screw-type drive mechanisms.
For high-throughput positioning applications, the short settling times, e g, 75ms for 5mm step are a real benefit.
