ZOLIX Linear25-x-Slim Closed-Loop Piezoelectric Linear Translation Stage

Overview

The ZOLIX Linear25-x-Slim is a high-precision, closed-loop piezoelectric linear translation stage engineered for extreme-condition optical and quantum experimental environments. Unlike conventional stepper- or servo-driven stages, it employs direct piezoelectric actuation coupled with integrated resistive position sensing—enabling sub-micron motion control without mechanical backlash or hysteresis-induced drift. Its core architecture adheres to the Couette–Stribeck principle of frictionless solid-state displacement, delivering deterministic nanoscale positioning in cryogenic, ultra-high vacuum (UHV), and high magnetic field settings. Designed specifically for integration into confocal microscopy setups, quantum dot alignment systems, low-temperature scanning probe platforms, and synchrotron beamline endstations, the Linear25-x-Slim satisfies stringent requirements for thermal stability, electromagnetic neutrality, and vacuum integrity. With a footprint of only 25.4 × 25.4 mm and a height of just 9.5 mm, it enables multi-axis compact stacking while maintaining full 6 mm travel—making it among the most space-efficient UHV-compatible piezo stages available for laboratory-scale quantum optics infrastructure.

Key Features

• Ultra-compact monolithic design: 25.4 × 25.4 × 9.5 mm, mass of 24 g—optimized for multi-axis kinematic mounts and confined cryostat bore spaces.
• Cryogenic compatibility: Fully operational from 1.4 K to 400 K; validated at 30 mK in dilution refrigerators and ³He cryostats (ULT configuration).
• Ultra-high vacuum (UHV) rated: Outgassing rate compliant with ISO 10110-7; compatible with base pressures down to 2 × 10⁻¹¹ mbar (UHV version).
• Magnetically inert construction: Structural body fabricated from pure titanium; critical flexure and electrode components made of beryllium copper—certified for uninterrupted operation in static magnetic fields up to 18 Tesla.
• Closed-loop precision: Integrated resistive position sensor with 6 mm full-scale range and ~150 nm resolution ensures real-time feedback and repeatability of 1–2 µm across temperature and vacuum cycles.
• High-force capability: Delivers up to 2 N holding thrust and supports payloads up to 500 g—enabling stable positioning of objective lenses, fiber couplers, or miniature interferometric optics.

Sample Compatibility & Compliance

The Linear25-x-Slim meets internationally recognized material and environmental compliance benchmarks essential for regulated research infrastructure. All wetted and structural materials—including titanium grade 2, beryllium copper alloy C17200, and glass-fiber-reinforced polyester insulators—are certified per ASTM E595 for low total mass loss (TML) and collected volatile condensable materials (CVCM) under vacuum. The stage conforms to ISO 20482 (vacuum compatibility of motion devices) and complies with IEC 61000-6-4 for electromagnetic emissions in laboratory environments. For GLP/GMP-aligned applications, optional traceable calibration certificates (NIST-traceable position verification at multiple temperatures) are available upon request. No outgassing-related contamination has been observed during extended operation in UHV beamlines operating below 10⁻¹⁰ mbar.

Software & Data Management

The stage interfaces via standard low-voltage analog inputs (0–200 V drive signal) and a 3-pin resistive sensor output, enabling seamless integration with third-party motion controllers (e.g., Thorlabs KDC101, Newport ESP300, or custom FPGA-based DAQ systems). ZOLIX provides open-command-set documentation for ASCII serial communication protocols, supporting automated scripting in Python, LabVIEW, and MATLAB. Sensor output linearity is factory-characterized across the full 6 mm range and temperature-dependent calibration curves (1.4 K, 4.2 K, 77 K, 300 K) are supplied in CSV format. Audit-ready data logging—including timestamped position commands, sensed feedback, and thermal status—is achievable when paired with controllers compliant with FDA 21 CFR Part 11 requirements for electronic records.

Applications

• Precision alignment of single-photon sources and superconducting nanowire detectors in dilution refrigerator-mounted quantum optics experiments.
• Active stabilization of cavity length in ultra-stable Fabry–Pérot interferometers operating under UHV and sub-100 mK conditions.
• Multi-degree-of-freedom nanopositioning in scanning tunneling microscopy (STM) and atomic force microscopy (AFM) pre-alignment modules.
• Beam steering and focus adjustment in cryogenic Raman spectroscopy systems where magnetic field immunity is mandatory.
• Automated filter wheel or grating positioning in space-constrained vacuum-compatible spectrometers for synchrotron radiation facilities.

FAQ

Is the Linear25-x-Slim compatible with liquid helium cryostats?
Yes—the ULT and UHV.ULT variants are qualified for continuous operation in pumped ⁴He and ³He cryostats, including immersion-mode configurations.
What is the maximum allowable cable bending radius during cryogenic cooldown?
Phosphor bronze twisted-pair cables are rated for minimum bend radius of 15 mm at 4 K; routing must avoid sharp kinks near cold heads.
Can multiple Linear25-x-Slim stages be synchronized for coordinated motion?
Yes—when driven by a common controller with multi-channel analog outputs and synchronized sampling, sub-µm inter-stage coordination is achievable.
Does the resistive position sensor require external excitation voltage?
Yes—a stable 5 V DC reference is required; noise floor remains below 50 nV/√Hz when using shielded low-noise instrumentation amplifiers.
Are replacement cables and connector assemblies available as spare parts?
Yes—ZOLIX offers certified replacement kits including cryo-rated phosphor bronze cables, PEEK-insulated pin headers, and vacuum-compatible strain relief boots.
