PI’s V-106 Quickscan series of PCI-card-driven, high-speed voice coil positioning stages are for high-dynamics precision motion control
PI (Physik Instrumente), a leading manufacturer of nanopositioning and precision motion-control equipment for bio/nanotechnology, photonics, semiconductor and life science applications, is introducing 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 precision stages are designed for high-dynamics precision motion control applications, such as those in biotechnology, laser beam control, scanning, optics, lens finishing, and fibre-optics.
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 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 of 75ms for 5mm steps are a real benefit.
The following features and benefits are offered by the V-106 Quickscan stages: frictionless voice coil linear motor drive for smooth, ripple-free motion; velocity up to 240mm/sec; scanning frequency several tens of Hertz; direct metrology linear encoder with 100nm resolution; travel ranges of 20mm and 6mm; precision cross-roller bearings for ultra-accurate and smooth motion; and cost-effective PCI-card controller with on-board amplifiers.
