Positioning stage promise speed and resolution
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
PI (Physik Instrumente) 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.
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.
Cost-effective PCI-bus motion controller card w/ 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 (~ 9.6inch/s).
Higher dynamics and lifetime than screw-type drive mechanisms.
V-106 QuickScanstages 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, e.g 75ms for 5mm step are a real benefit.
