piezosystem jena has expanded its PXY series and introduces an XY plane nanopositioning and microscanning stage featuring a wide center clearance.
The PXY 201 CAP offers a clearance of 30x30mm² and a motion range of up to 250 microns in open loop and up to 200 microns in closed loop. The PXY 201 CAP can be equipped with an integrated high resolution capacitive feedback sensor. Creep and hystersis can be compensated by using the stage in combination with a matching amplifier from piezosystem jena.
The system provides supreme position stability, linearity, repeatability and accuracy. Furthermore, digital amplifiers from piezosystem jena allow optimization of the electrical parameters during system operation for the best performance under the conditions of operation.
Thanks to the FEA-optimized guidance, the system features supreme trajectory accuracy. The stage is very robust against high loads due to the frame design of the guidance. To minimize overshooting and to shorten settling while scanning, the PXY 201 line is equipped with an internal passive damping system. Also any kind of position noise is reduced.
Vacuum and cryogenic performances are available on request as well as, body material variations of invar, super invar, aluminum or titanium.
With all these characteristics the PXY 201 CAP is an excellent choice for applications such as scanning microscopy, surface analysis, metrology and alignment as well as wide range nanopositioning and micro scanning requirering sub-nm accuracy and free aperture too.
