Klocke Nanotechnik Nano Positioning System

Overview

The Klocke Nanotechnik Nano Positioning System is a high-precision, piezoelectric-driven motion platform engineered for sub-nanometer spatial control in demanding scientific and industrial environments. Based on direct-drive capacitive-sensor feedback and low-drift ceramic actuator architecture, it operates on the principle of electrostrictive displacement amplification—enabling deterministic, hysteresis-free positioning without mechanical transmission elements. Unlike conventional motorized stages or voice-coil actuators, this system delivers true atomic-scale resolution with zero backlash, thermal drift compensation, and immunity to electromagnetic interference. It is specifically developed for integration into ultra-high-vacuum (UHV) chambers, cryostats operating below 4 K, and high-field magnet systems (up to 16 T), where conventional positioning solutions fail due to outgassing, thermal contraction mismatch, or Lorentz-force-induced instability.

Key Features

• True nanometer-scale open-loop resolution of 2 nm, with closed-loop sensor resolution better than 10 nm using integrated capacitive or interferometric position sensing
• Multi-axis configurability: modular XYZ linear stages, rotary (Θ/Φ) platforms, and hybrid coarse/fine architectures supporting simultaneous macro- and micro-positioning within a single unit
• Extreme-environment compatibility: all-metal vacuum-sealed construction; optional Invar or titanium frames; bakeable to 150 °C; certified for UHV (<1×10⁻¹⁰ mbar) and liquid nitrogen immersion
• No high-voltage drive required: operates from standard ±10 V analog input or digital EtherCAT interface, reducing EMI risk and simplifying integration with SEM, TEM, FIB, and AFM control ecosystems
• High static load capacity up to 2 kg—exceeding self-weight by 3–5×—with maintained positional stability over extended dwell times (>24 h)
• Zero mechanical hysteresis and negligible thermal drift (<0.1 nm/°C over operational range), validated per ISO 230-2 Annex B test protocols

Sample Compatibility & Compliance

The Klocke Nano Positioning System is compatible with a broad spectrum of sample carriers, probe holders, and detector mounts used in electron microscopy, synchrotron beamlines, quantum device fabrication, and nanomechanical testing. Its mechanical interface conforms to standard M3/M4 tapped holes and kinematic mounting patterns (e.g., Ø6 mm dowel pin alignment). All variants comply with ISO 14001 environmental manufacturing standards and meet material outgassing requirements specified in ESA ECSS-Q-ST-70-02C for space-qualified instrumentation. Vacuum-rated models are tested per ASTM E595 for total mass loss (TML) and collected volatile condensable materials (CVCM), reporting TML < 0.5% and CVCM < 0.1%. For regulated laboratories, optional firmware supports audit-trail logging and user-access controls aligned with FDA 21 CFR Part 11 and EU Annex 11 principles.

Software & Data Management

The system integrates natively with Klocke’s NanoControl Suite—a cross-platform application supporting Windows, Linux, and real-time RTX environments. It provides deterministic motion sequencing (sub-millisecond jitter), synchronized trigger I/O for external detectors (e.g., photon counters, lock-in amplifiers), and programmable trajectory generation (sine, sawtooth, Lissajous, custom CSV-defined paths). Data export supports HDF5 and MAT formats for MATLAB/Python post-processing. Optional SDKs enable integration with LabVIEW, Python (PyVISA, NumPy), and EPICS-based control frameworks. Closed-loop operation includes real-time error correction with configurable PID tuning and dynamic bandwidth adjustment (1 Hz to 5 kHz), ensuring stability under variable inertial loading conditions.

Applications

• In situ TEM/SEM nanomanipulation: precise tip-sample approach, electrical contact formation, and mechanical property mapping at atomic scale
• Quantum transport experiments: positioning of gate electrodes, superconducting resonators, or spin qubit substrates inside dilution refrigerators
• Nanoimprint lithography alignment: sub-10 nm overlay accuracy across 70 mm travel range with thermal drift compensation
• Interferometric metrology: active vibration cancellation and path-length stabilization in gravitational wave detector prototypes
• Biophysical force spectroscopy: integration with optical tweezers or magnetic tweezers for dual-mode pN–nN force calibration
• Advanced semiconductor metrology: wafer-stage positioning for maskless e-beam lithography and defect review tools

FAQ
