Positioning stage with speed and precision

The V-106 QuickScan series of PCI-card-driven, high-speed voice coil positioning stages provide up to 20 mm (0.8 inches) of travel and resolution to 100 nanometers

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 20 mm (0.8 inches) 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 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 100 nanometer resolution, the systems provide extremely smooth motion with velocities to 240 mm /s (9.6 inch/s).

V-106 QuickScan stages achieve significantly higher dynamics than leadscrew-based units, with scanning frequencies to 20 Hz 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 75 ms for 5 mm step, are a real benefit.

* Frictionless voice-coil linear motor drive for smooth, ripple-free motion.

* Velocity up to 240 mm/sec (9.6 inch/sec).

* Scanning frequency several 10s of Hz.

* Direct metrology linear encoder with 100 nanometer resolution.

* Travel ranges of 20 mm and 6 mm.

* Precision cross-roller bearings for ultra-straight and smooth motion.

* Cost-effective PCI-card controller with on-board amplifiers.
