Overview
The ZOLIX Linear25-x-Pro is a high-performance, closed-loop piezoelectric linear translation stage engineered for extreme-condition optical and quantum experimental environments. Based on the robust Couette-type piezo actuation principle—where controlled expansion of stacked piezoceramic elements drives precise nanoscale displacement—the Linear25-x-Pro delivers deterministic motion without mechanical backlash or hysteresis-induced drift. Its monolithic titanium and beryllium copper construction ensures non-magnetic operation, thermal stability across cryogenic regimes, and compatibility with ultra-high vacuum (UHV) and ultra-low temperature (ULT) infrastructure. Designed explicitly for integration into dilution refrigerators, helium-3 cryostats, and superconducting magnet systems, this stage supports sub-micron positioning repeatability under static and dynamic loads up to 300 g while maintaining structural integrity in magnetic fields up to 18 Tesla.
Key Features
- Ultra-compact footprint: 25 × 25 × 17 mm — optimized for space-constrained optical tables, cryogenic probe stations, and multi-axis nanopositioning stacks.
- Full UHV/ULT compatibility: Validated at pressures down to 2 × 10⁻¹¹ mbar and operational from 1.4 K to 400 K; optional configurations include HV (high vacuum), ULT (ultra-low temperature), and UHV (ultra-high vacuum) variants.
- Non-magnetic architecture: Entire structural body fabricated from pure titanium and beryllium copper alloys — certified for use in high-field MRI, NMR, and quantum computing testbeds requiring zero magnetic interference.
- Closed-loop feedback control: Integrated resistive position sensor with 6 mm full-scale range and ~150 nm intrinsic resolution enables real-time error correction and achieves 0.1 µm minimum programmable step size.
- High-force, low-thermal-drift actuation: Delivers up to 3 N holding force and 300 g payload capacity with minimal heat dissipation (<15 mW at hold), critical for minimizing thermal load in millikelvin environments.
- Customizable interconnect system: Phosphor bronze twisted-pair cable (20 cm standard length), glass-fiber-reinforced polyester insulators, and BeCu/PEEK pin headers ensure reliable signal integrity and mechanical decoupling under thermal cycling.
Sample Compatibility & Compliance
The Linear25-x-Pro meets stringent requirements for regulated research infrastructure. Its material composition and surface finish comply with ASTM E595 for outgassing performance in vacuum applications. The absence of ferromagnetic components satisfies ISO 14644-1 Class 3 cleanroom compatibility when operated in inert-gas purged enclosures. For users operating under GLP or GMP frameworks, the stage’s closed-loop sensor output supports audit-ready traceability when paired with compliant DAQ systems (e.g., National Instruments PXI platforms with calibrated analog input modules). While not FDA-certified per se, its design adheres to principles outlined in USP for analytical instrument qualification—particularly for installation qualification (IQ) and operational qualification (OQ) protocols involving positional accuracy verification at multiple setpoints across the travel range.
Software & Data Management
The Linear25-x-Pro interfaces via standard analog ±10 V position command and feedback signals, enabling seamless integration with LabVIEW, MATLAB, Python (via NI-DAQmx or PyVISA), and third-party motion controllers (e.g., Thorlabs Kinesis, Newport ESP300). ZOLIX provides open-source configuration templates for PID tuning and trajectory generation—including trapezoidal, S-curve, and custom waveform profiles—to minimize settling time and overshoot. All sensor data streams support timestamped logging at up to 1 kHz sampling rate, facilitating post-acquisition analysis of thermal drift, mechanical compliance, and long-term stability. Firmware updates are delivered via USB-C diagnostic port and retain full backward compatibility with existing controller firmware versions.
Applications
- Precision alignment of single-photon sources and superconducting nanowire detectors in quantum optics setups.
- Active stabilization of interferometer arms in cryogenic gravitational wave detector prototypes.
- Position-controlled sample scanning in scanning tunneling microscopy (STM) and atomic force microscopy (AFM) pre-alignment stages.
- Dynamic focus adjustment of fiber-coupled laser diodes inside dilution refrigerator optical access ports.
- Multi-axis nanopositioning for cavity optomechanics experiments requiring sub-100 nm repeatability over extended thermal cycles.
- Automated calibration of cryogenic photodetector responsivity using reference light sources mounted on adjacent Linear25-x-Pro units.
FAQ
What vacuum level is the Linear25-x-Pro rated for, and how is outgassing validated?
The UHV variant is rated for continuous operation at ≤2 × 10⁻¹¹ mbar. Outgassing rates are measured per ASTM E595 using a residual gas analyzer (RGA) after 24-hour bakeout at 120 °C; total mass loss (TML) <0.5% and collected volatile condensable materials (CVCM) <0.05% are consistently achieved.
Can the stage be operated in pulsed magnetic fields above 18 T?
Static field tolerance is verified up to 18 T. Pulsed fields exceeding this threshold may induce eddy-current heating in conductive components; users must perform empirical testing with pulse duration and rise-time parameters relevant to their specific magnet system.
Is the 0.1 µm minimum step size guaranteed across the full 6 mm travel range?
Yes—closed-loop operation maintains 0.1 µm programmable resolution across the entire range. Open-loop operation exhibits higher hysteresis and is not recommended for metrology-grade applications.
How does thermal contraction affect calibration between 300 K and 10 mK?
Titanium’s coefficient of thermal expansion (CTE ≈ 8.6 × 10⁻⁶ /K) results in ~0.15 mm net contraction over this range. ZOLIX provides CTE-compensated calibration curves downloadable from the support portal for model-based correction in software-defined motion profiles.
Are replacement cables and connector assemblies available as spare parts?
Yes—phosphor bronze twisted-pair cables (custom lengths up to 1 m), BeCu/PEEK pin headers, and vacuum-compatible feedthroughs are stocked and shipped with RoHS-compliant documentation and material certificates.
