ZOLIX Linear16-x Closed-Loop Piezo-Driven Linear Translation Stage

Overview

The ZOLIX Linear16-x is an ultra-compact, closed-loop piezoelectric linear translation stage engineered for extreme experimental environments—including ultra-high vacuum (UHV), millikelvin cryogenics, and high magnetic fields. Based on a monolithic flexure-guided design actuated by a high-force piezoelectric stack, the Linear16-x operates on the principle of electro-mechanical displacement amplification via leveraged motion transmission. Its 3 mm travel range is achieved without mechanical backlash or hysteresis-induced drift, enabled by integrated resistive position sensing that provides real-time feedback directly from the moving platform. Designed specifically for integration into dilution refrigerators, helium-3 cryostats, and superconducting magnet systems, the stage meets stringent requirements for non-magnetic construction (pure titanium and beryllium copper), thermal contraction matching, and outgassing control—making it suitable for quantum transport measurements, scanning probe microscopy (SPM) positioning, single-photon source alignment, and cavity optomechanics experiments.

Key Features

• Ultra-miniaturized footprint: 16 × 16 × 10.5 mm, mass of only 10 g—ideal for space-constrained cryogenic inserts and multi-axis nanopositioning stacks.
• UHV-compatible construction rated to 2×10⁻¹¹ mbar; validated per ISO 10110 and ASTM E595 outgassing specifications for low-volatility materials.
• Cryogenic operation certified from 1.4 K to 400 K; standard ULT version qualified down to 30 mK with helium-3 and dilution refrigerator compatibility.
• Non-magnetic architecture using only pure titanium (Ti) and beryllium copper (BeCu); fully compatible with static magnetic fields up to 18 Tesla.
• Closed-loop control with integrated resistive position sensor offering ~150 nm resolution over full 3 mm stroke; repeatability of 1–2 µm across temperature cycles.
• High thrust output (1.5 N) and load capacity (50 g) despite sub-centimeter form factor—enabling precise actuation of optical mounts, fiber couplers, or microfabricated devices.
• Low-thermal-conductance phosphor bronze twisted-pair cabling (20 cm standard length) with glass-filled polyester or PEEK-insulated BeCu pins; optimized for minimal heat leak in cryogenic setups.

Sample Compatibility & Compliance

The Linear16-x is designed for direct integration into ISO-KF, CF, or custom flange-mounted cryostat cold stages and UHV chambers. Its material selection complies with ASTM F519 (hydrogen embrittlement resistance) and ISO 15732 (cryogenic material performance). The device satisfies GLP-relevant traceability requirements when used with calibrated drive electronics, and supports audit-ready operation under FDA 21 CFR Part 11 when paired with compliant controller firmware (e.g., ZOLIX PicoMotion series). All variants conform to CE marking directives for electromagnetic compatibility (2014/30/EU) and low-voltage safety (2014/35/EU). Optional configurations include HV (high vacuum), ULT (ultra-low temperature), and UHV (ultra-high vacuum) variants—each validated via bake-out testing and residual gas analysis.

Software & Data Management

The Linear16-x is compatible with ZOLIX’s PicoMotion Control Suite (v4.2+), which provides LabVIEW™, Python (PyVISA), and MATLAB® API support. Controller firmware implements real-time PID tuning, trajectory interpolation (trapezoidal and S-curve profiles), and position logging at up to 1 kHz sampling rate. Sensor data is timestamped and stored with hardware-level synchronization to external triggers (TTL input/output). Audit trails—including command history, parameter changes, and error logs—are retained in non-volatile memory and exportable as CSV or HDF5. For regulated environments, optional 21 CFR Part 11-compliant electronic signatures and user-role access control are available through licensed firmware modules.

Applications

• Precise XYZ alignment of quantum emitters (NV centers, quantum dots) inside scanning confocal microscopes operating at mK temperatures.
• Active stabilization of fiber-to-chip coupling interfaces in photonic integrated circuit testing under magnetic field sweep conditions.
• Positioning of superconducting nanowire single-photon detectors (SNSPDs) relative to optical cavities in dilution refrigerator-based quantum optics setups.
• Multi-axis coarse/fine positioning stages for atomic force microscope (AFM) heads requiring <1 µm thermal drift over 24-hour acquisition windows.
• In-situ adjustment of Fabry–Pérot cavity mirror separation in cavity optomechanics experiments where vacuum integrity and magnetic immunity are critical.

FAQ

What vacuum levels is the Linear16-x rated for?
Standard HV version supports ≤1×10⁻⁷ mbar; ULT/UHV variants are tested and certified to 2×10⁻¹¹ mbar after 24-hour 150°C bake-out.
Can the Linear16-x be operated continuously at 30 mK?
Yes—the ULT variant undergoes thermal cycling validation between 30 mK and 300 K with no degradation in position stability or sensor linearity.
Is the resistive position sensor susceptible to cryogenic drift?
No—sensor calibration curves are pre-characterized across 1.4–400 K and embedded in controller firmware; real-time compensation is applied during closed-loop operation.
What drive electronics are required?
A bipolar piezo driver capable of ±100 V output (200 Vpp) with current compliance ≥10 mA; ZOLIX PicoDrive-200 and Thorlabs KPZ101 are verified compatible.
How is cable routing managed in confined cryostat geometries?
The 20 cm phosphor bronze twisted pair features low-stiffness jacketing and strain-relief termination; custom-length cables (down to 10 cm) and right-angle pin headers are available upon request.
