Linearity and repeatability in nanopositioning systems would not be possible without highest-resolution measuring devices.

When accuracy in the range of a few nanometers and below is needed, a position measurement method that can detect motion in this range becomes required. To select the most suitable method the importaint factors to consider are linearity, resolution (sensitivity), stability, bandwidth, cost and the ability to directly record the motion of the platform.

To minimize the effect that the sensors has when in contact with the movable parts you will mostly find noncontact measurement methods and as small sensors as possible that may not heat up. Via our supplier, Physik Instrumente we offer the following sensor types for our nanopositioning systems.
