Fast linear stage with nanometre resolution
16 August 2015
The PIMag V-551 linear stage from Physik Instrumente (PI) achieves a travel accuracy of 1µm over a travel range of 100mm, and is suitable for scanning applications that require both high accelerations and high constant velocities.
The 160mm wide stage can be fitted with a motor providing 100N or 200N peak force and configured for travel ranges of 50, 130 or 230mm. In addition, the working range can be adapted to the respective application using adjustable mechanical hard stops. The positioning accuracy can also be adjusted according to the measuring system used.
When operated in conjunction with PI's C-891 motion controller, the standard version of the ironless magnetic direct offers a positioning resolution of 1.7nm and a repeatability of <20nm. The highest achievable velocity is 500mm/s.
An absolute encoder is integrated as standard, which means that a reference move is not necessary during switch-on. Used in conjunction with PI motion controllers and optional high-resolution incremental encoders, resolutions of up to 0.03nm are possible.
