Physik Instrumente (PI) has launched a product line of linear nanopositioning systems, the P-630 stages, for a range of applications including use in sensor heads or precision motion of objects in optical and tactile metrology, as well as for microstructuring.
With travel ranges up to 80µm and a direct piezo actuator drive, the compact positioning stages reach high scanning frequencies and settling times of a few milliseconds. At a width of 50mm, their clear aperture is relatively large with a diameter of 30mm.
The drive technology of the systems is based on all-ceramic insulated Picma piezo actuators. They have a proven longer lifetime and higher reliability than conventional polymer-insulated actuators.
The P-630 stages achieve nanometre-precise positioning accuracy and stability is using an integrated capacitive position sensor.
Optimum control properties are ensured via the high performance single-channel E-709.CHG motion controller. Its digital technology allows for refined linearisation algorithms to improve accuracy; the operating parameters can easily be optimised via software.
