SHREWSBURY, Mass., Aug. 25, 2026 — PI (Physik Instrumente), a global leader in piezo nanopositioning and air bearing technology, offers the P-733 XYZ piezo nanopositioning stage, delivering 0.1 nm (1 Å) positioning resolution for demanding applications in super-resolution microscopy, atomic force microscopy (AFM), surface nanometrology, and advanced imaging.
The P-733 combines frictionless flexure guidance with high-accuracy capacitive position feedback to achieve sub-nanometer positioning performance and highly repeatable motion. Travel ranges of up to 100 × 100 µm in X and Y and 10 µm in Z enable precision sample scanning and measurement across comparatively large areas. A 50 × 50 mm clear aperture supports transmitted-light microscopy and other optical imaging techniques.
High-stiffness direct-drive version for maximum throughput
For applications that demand the highest scanning speeds and fastest settling times, the P-733.3DD direct-drive version provides 30 × 30 × 10 µm travel with the same 0.1 nm resolution. Its high-stiffness design supports rapid scanning and dynamic positioning, with resonant frequencies exceeding 1 kHz.
The stage architecture incorporates parallel kinematics and parallel metrology, ensuring that all motion axes are measured relative to a common fixed reference. This design actively compensates for crosstalk and guiding errors, helping maintain nanometer-level tracking accuracy during high-speed scanning and precision measurement tasks.
Key features:
- 0.1 nm (1 Å) positioning resolution
- UHV-compatible and nonmagnetic versions available
- XYZ motion with travel ranges up to 100 × 100 × 10 µm
- 50 × 50 mm clear aperture for transmitted-light microscopy
- Capacitive feedback sensors with up to 99.97% motion linearity
- Parallel kinematics and parallel metrology for enhanced multi-axis accuracy
- High-stiffness direct-drive variant for fast scanning and shortest step-and-settle times
- Ideal for wafer metrology, super-resolution microscopy, nanoimprinting, surface metrology, and image stabilization
- Wear-Free Design for Long-Term Stability
The P-733 employs wear-free, zero-play flexure guides and PICMA multilayer piezo actuators, eliminating mechanical friction and backlash. Noncontact capacitive sensors provide highly linear position measurement with exceptional long-term stability and typical linearity of 99.97%.
Applications and industries served
The P-733 is designed for a broad range of industrial and scientific applications, including super-resolution and confocal microscopy, AFM, surface characterization, wafer positioning, nanoimprinting, micromanipulation, precision optics and image stabilization. Ultra-high-vacuum-compatible and nonmagnetic configurations are available for specialized environments.
