NPS-X-28C Nanopositioning Stage Datasheet

The NPS-X-28C was originally developed for high speed, ultra precision MR head and disk drive testing.

It’s small size and millisecond response time is ideal for applications where high reliability and throughput are essential.
 A low moving mass and high stiffness combine to offer extremely high bandwidth.

The capacitive sensor design provides the sub-nanometer displacement measurement and closed-loop feedback over a range in excess of 28 microns. Flexure guidance offers high purity of motion, with parasitic motion. Combined with Queensgate’s digital closed-loop controllers, the NPS-X-28C can achieve millisecond response and settle times.

  • >28μm travel with sub-nanometer resolution
  • First resonant frequency >4.5KHz
  • Bandwidths up to 2KHz
  • In-situ scanning and stepping response optimization
  • Robust and reliable for production test
  • Plug and play facilities for low down-time
  • MR head and disk drive testing
  • Interferometry
  • Metrology
  • AFM Z axis

NPC-D-5200 or NPC-D-6330 series controllers are designed specifically to control Queensgate’s Nanometer Precision Mechanisms. They use modern DSP techniques and combine piezo drive amplifiers, capacitance position sensing circuitry and servo control capability. Use of PID (proportional integral differential) feedback terms greatly improves settle times and minimizes
the effect of mechanical resonances. The virtual front panel software facilitates user control of all operating parameters, including PID loop set up.
