V-106 Voice-Coil Scanning System

  • Fast Scanning & Positioning
  • X and XY Versions
  • Velocity up to 50 mm/s
  • Travel range: 6 mm
  • Resolution: 0.1 µm
  • PC-Card Servo-Controller with Windowsä software


The V-106 Voice-Coil Scanning and Positioning System is designed for applications where small samples have to be positioned or scanned with high velocity and high resolution. It provides superior responsiveness over micropositioners with conventional screw drives.

The mechanics (X or XY stage) are driven by an integrated non-contact, zero-friction voice-coil actuator. Scan velocities up to 50 mm/sec over a range of 6 mm are feasible (see V-102 QuickScan System for velocity up to 250 mm/sec). Integrated linear encoders provide position resolution of 0.1 µm. Non-contact hall effect origin switches (repeatability better than 1 µm) are standard, too.

The digital controller comes on an ISA-Bus compatible PC-plug-in-card and features on-board linear amplifiers for two individual axes, a 32 bit PID-V-ff servo system and other goodies such as I/O lines and hardware interrupt capability.

A mounting plate and software tools (LabView drivers, Libraries in C, Pascal, Basic...) are included in the system.

Application examples:
Semiconductor testing, medical analytical equipment, micro dispensing applications, optical device testing, lens testing, scanning microscopy, micro manufacturing.
