  • Screening
  • Interferometry
  • Measuring technology
  • Autofocus systems
  • Biotechnology
  • Semiconductor tests

Subnanometer resolution with capacitive sensors

  • Capacitive sensors measure with subnanometer resolution without contacting. They guarantee excellent linearity of motion, long-term stability, and a bandwidth in the kHz range.

High guiding accuracy due to zero-play flexure guides

  • Flexure guides are free of maintenance, friction, and wear, and do not require lubrication. Their stiffness allows high load
    capacity and they are insensitive to shock and vibration. They are 100 % vacuum compatible and work in a wide temperature range.

Automatic configuration and fast component exchange

  • Mechanics and controllers can be combined as required and exchanged quickly. All servo and linearization parameters are stored in the ID chip of the Sub-D connector of the mechanics. The autocalibration function of the digital controllers uses this data each time the controller is switched on.

Maximum accuracy due to direct position measuring

  • Motion is measured directly at the motion platform without any influence from the drive or guide elements. This allows
    optimum repeatability, outstanding stability, and stiff, fast-responding control.
