Nanopositioning Stage, 400 µm, Strain-gauge

The NPX400SG Nanopositioning Linear Stage is a 400 µm travel piezo-based linear stage providing nanometer resolution motion in the X axis. It is ideally suited for nanopositioning of small components such as mirrors, fibers, laser diodes, micro-optics, sensors, or cellular samples. Applications include optical delay lines, path length changes of interferometers, laser lithography, scanning microscopy, and patch-clamping, among others. NPX stages feature highly reliable, multi-layer, low-voltage piezoelectric transducer (PZT) stacks for high-duty cycle operations. A sophisticated, FEA-optimized, parallelogram solid state flexure guide system ensures perfect parallel motion. Due to the frictionless guide, NPX stages are maintenance-free, are not subject to wear and provide rapid response and fast settling performance making them suitable for use in dynamic processes such as high-frequency error compensation, tracking, fast stepping or continuous scanning.
The closed-loop version features a high res strain-gauge position sensor for highly accurate and repeatable motion, that also compensates for actuator creep. The sensors are built in a full Wheatstone bridge design. It can be operated in either open or closed-loop control. Fastening is easy with a number of threads and alignment pin holes at the top and bottom plates. For mounting to optical tables or other components with the same hole grid, use adapter plate NPX-BP. Like with all piezo flexure devices, excessive moment loads and side forces acting between the top plate and the housing should be avoided during fastening.
