Stages are designed for dynamic precision

The V-106 QuickScan series of PCI-card-driven, high-speed voice coil positioning stages provides up to 20mm of travel and resolution to 100nm.

PI (Physik Instrumente) offers the V-106 QuickScan series of PCI-card-driven, high-speed voice coil positioning stages, providing up to 20mm of travel and resolution to 100nm.

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 fibre optics.

QuickScan systems are driven by a PCIbus motion controller card with onboard linear servo amplifiers.

Based on a frictionless, backlash-free, voice coil linear motor drive and a high-precision optical encoder featuring 100nm resolution, the systems provide extremely smooth motion with velocities to 240mm/s.

V-106 QuickScan stages achieve significantly higher dynamics than leadscrew-based units, with scanning frequencies to 20Hz and above for small loads.

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, eg 75ms for 5mm step, are a real benefit.
