high speed positioner
The nanoX400/400SG/400CAP one axis, low voltage, linear stage is a development within our ultra-fast nanoX line. It provides a long positioning and scanning range of up to 480 microns. The centrally located free aperture allows laser optical applications through the stage. This is also possible when stacking them in an XY configuration. Due to FEA-optimization, the nanoX400 provides the highest dynamical performance and excellent guiding accuracy. This is accomplished even with high mass loads in a very compact package. Our optimization also incorporates excellent temperature compensation properties for the trajectory of the stage.
The sophisticated monolithic guidance design of the solid flexure hinges means the trajectory is free of mechanical play and friction - a feature of all psj-stages.
Please note: Based on solid-state phenomena, piezoactuators generate pressure forces to affect the leverage geared motion. The ceramic's extension is nearly linear to the applied electric field, but hysteresis and creep still exist. Piezoelectric geared devices are neither affected by nor produce magnetic fields. In cryogenic environments they function down to almost zero Kelvin. This low temperature is associated with linear decreasing extension behavior. In vacuum conditions, piezoactuators can be used at pressures below 10 Pa.
Because of the greatly reduced dielectric breakdown strength of air, they should not be operated at pressures ranging from 10 Pa up to 10 kPa. To avoid creep and hysteresis, the nanoX 400SG / 200CAP is equipped with a high resolution measurement sensor.
In combination with a psj-controller, high stability, linearity, repeatability, and accuracy are achieved during closed loop operation. The compact design and the raster pin and drill holes for mounting allow an easy integration of the nanoX into your existing assembly.
Vacuum and cryogenic versions are available on demand, as well as body material variations of invar, superinvar, aluminum, or titanium.
