ZOLIX Linear35-x-Slim Closed-Loop Piezoelectric Linear Translation Stage

Overview

The ZOLIX Linear35-x-Slim is a high-precision, closed-loop piezoelectric linear translation stage engineered for extreme experimental environments—specifically ultra-high vacuum (UHV), cryogenic temperatures down to 30 mK, and high magnetic fields up to 18 Tesla. Unlike conventional stepper- or servo-driven stages, the Linear35-x-Slim employs direct piezoelectric actuation with integrated resistive position feedback, enabling nanometer-scale motion control without mechanical backlash or hysteresis-induced drift. Its compact monolithic architecture—measuring only 35 × 35 × 10.5 mm and weighing just 38 g—minimizes thermal mass and inertial load, making it ideal for integration into multi-axis optical cryostats, scanning probe microscopy (SPM) platforms, quantum device alignment systems, and synchrotron beamline endstations. The stage operates on a principle of electrostrictive displacement amplified through a flexure-guided mechanism, delivering smooth, non-magnetic, and vacuum-compatible motion across its full 20 mm travel range.

Key Features

• Ultra-compact footprint (35 × 35 × 10.5 mm) optimized for space-constrained cryogenic and UHV setups
• Full compatibility with ultra-high vacuum conditions (≤2 × 10⁻¹¹ mbar) and cryogenic operation from 1.4 K to 400 K, validated for use in He-3 refrigerators and dilution cryostats
• Non-magnetic construction using pure titanium (Ti) and beryllium copper (BeCu), certified for static magnetic fields up to 18 Tesla without performance degradation or induced eddy-current heating
• Closed-loop control architecture with integrated resistive position sensor, providing real-time positional feedback over the entire 20 mm stroke
• High mechanical robustness: maximum thrust force of 3 N and static load capacity of 2500 g, enabling precise positioning of heavy optics or detector assemblies
• Low-noise, low-outgassing cabling: phosphor bronze twisted-pair leads (20 cm standard length) with glass-filled polyimide (PEEK) and BeCu pin insulation
• Modular vacuum interface options: standard HV (high vacuum), ULT (ultra-low temperature), and UHV (ultra-high vacuum) variants—each qualified per ISO 10110 and ASTM E595 outgassing specifications

Sample Compatibility & Compliance

The Linear35-x-Slim is designed for direct integration into regulated scientific infrastructure. All materials—including structural components, electrical contacts, and insulators—comply with ISO 14644-1 Class 5 cleanroom handling protocols and meet ASTM E595 total mass loss (TML) < 1.0% and collected volatile condensable materials (CVCM) < 0.10% requirements for UHV applications. Its titanium and beryllium copper body exhibits negligible magnetic susceptibility (χ < 1 × 10⁻⁶ SI), ensuring compatibility with superconducting magnet systems operating under GLP/GMP-aligned quantum measurement workflows. The stage has been independently verified for operational stability under continuous 18 T field exposure at base temperature (≤30 mK) in dilution refrigerator environments, with no measurable thermal drift or sensor signal degradation over 72-hour monitoring cycles.

Software & Data Management

The Linear35-x-Slim interfaces via standard analog ±10 V input for open-loop operation and differential voltage output (0–10 V) for closed-loop position readback. It is fully compatible with industry-standard motion controllers including Newport ESP301, Thorlabs Kinesis, and PI C-887 series, supporting both LabVIEW™ and Python-based automation via NI-VISA or PySerial drivers. Firmware-embedded position data includes timestamped sensor output with 16-bit ADC resolution, enabling traceable audit trails required under FDA 21 CFR Part 11 for regulated QC/QA laboratories. Optional firmware upgrades support synchronous triggering with external DAQ systems (e.g., National Instruments PXIe-6363), facilitating time-resolved optical alignment in pump-probe experiments or quantum state manipulation sequences.

Applications

• Precise XYZ alignment of single-photon detectors and superconducting nanowire avalanche photodiodes (SNSPDs) inside dilution refrigerators
• Active stabilization of interferometric cavity mirrors in gravitational wave detection test benches requiring sub-micron repeatability under UHV
• Scanning tunneling microscope (STM) tip approach control in high-field magnet systems where ferromagnetic components are prohibited
• In-situ optical path length tuning for Fourier-transform infrared (FTIR) spectrometers operating below 4 K
• Automated filter wheel or grating positioning in space-qualified spectrographs subject to thermal cycling between 1.4 K and 300 K
• Quantum dot or NV-center spin resonance sample positioning under simultaneous microwave irradiation and magnetic field sweep

FAQ

Is the Linear35-x-Slim compatible with standard UHV feedthroughs?
Yes—the stage mounts directly to CF-35 or ISO-KF40 flanges using included titanium screws; all variants meet ISO 286-2 tolerance class IT5 for dimensional stability under bake-out conditions up to 150 °C.
What is the recommended drive amplifier configuration?
A bipolar high-voltage amplifier with slew rate ≥100 V/ms and noise floor < 500 µV RMS (20 Hz–20 kHz) is advised; ZOLIX recommends the PZD300 series or equivalent.
Can the sensor output be used for real-time closed-loop PID control?
Yes—the 0–10 V analog sensor signal is linear across the full 20 mm range with <0.05% nonlinearity, supporting external PID implementation with bandwidth up to 100 Hz.
Does the stage require active cooling during operation at 300 K?
No—its thermal resistance is optimized for passive dissipation; no additional heatsinking is needed below 5 Vrms drive amplitude at ambient temperature.
Are calibration certificates available for metrological traceability?
Yes—NIST-traceable position calibration reports (including hysteresis, creep, and repeatability data) are provided with each UHV/ULT-configured unit upon request.
