Overview
The ZOLIX Linear55-x-Pro is a high-performance, motorized linear translation stage engineered for extreme-condition optical and quantum physics experiments. Based on piezoelectric inertial drive (stick-slip) actuation with integrated resistive position feedback, it delivers precise, repeatable, and drift-free motion in environments where conventional stepper or servo-driven stages fail—namely ultra-high vacuum (UHV), millikelvin cryogenics, and high magnetic fields. Its monolithic titanium and beryllium copper construction ensures non-magnetic operation up to 18 Tesla, zero outgassing, and thermal contraction compatibility across the full 1.4–400 K range. With a compact footprint of 55 × 55 × 10.5 mm and a mass of only 200 g, the Linear55-x-Pro is optimized for integration into multi-axis cryostat feedthroughs, scanning probe microscope (SPM) head assemblies, and quantum optics vacuum chambers.
Key Features
- Ultra-compact form factor (55 × 55 × 10.5 mm) with 25 mm travel and 500 g load capacity
- UHV-rated design certified to 2 × 10⁻¹¹ mbar; compatible with bake-out protocols up to 150 °C
- Cryogenic operation from 1.4 K (dilution refrigerator base temperature) to 400 K; validated down to 30 mK in He-3 systems
- Non-magnetic architecture using pure titanium body and beryllium copper flexures and electrical contacts — fully compatible with 18 T superconducting magnets
- Closed-loop control via integrated resistive position sensor with ~150 nm resolution and 1–2 µm repeatability
- High-thrust output (5 N) enabling stable positioning under mechanical preload or optical trap coupling
- Low-noise phosphor bronze twisted-pair cabling (20 cm standard) with glass-fiber-reinforced polyimide (PEEK) insulators and BeCu pins
- Modular interface: 2-pin basic drive, 7-pin advanced mode (for velocity profiling and real-time diagnostics), plus 3-pin analog sensor output
Sample Compatibility & Compliance
The Linear55-x-Pro meets stringent requirements for use in regulated and research-grade instrumentation. It complies with ISO 10110-7 (optical component mounting), ASTM E595 (outgassing testing for space applications), and is routinely deployed in setups requiring adherence to GLP and GMP-aligned lab practices. Its UHV-compatible surface finish (Ra < 0.2 µm), helium-leak-tested housing, and absence of organic adhesives or lubricants ensure long-term stability in cleanroom and quantum computing environments. The stage is suitable for mounting optical components (lenses, mirrors, fiber couplers), SPM tips, single-photon detectors, and microwave resonators—without introducing magnetic hysteresis, thermal drift, or vacuum contamination.
Software & Data Management
The Linear55-x-Pro supports analog voltage input (0–10 V) for open-loop operation and provides ratiometric analog output (0–10 V) proportional to absolute position. For closed-loop integration, it interfaces seamlessly with standard motion controllers supporting analog PID loops (e.g., Thorlabs KDC101, Newport ESP301, or custom LabVIEW/Python-based DAQ systems). Firmware-agnostic operation eliminates vendor lock-in; position data can be logged with timestamped, traceable audit trails required under FDA 21 CFR Part 11 for instrument qualification in metrology labs. Optional digital upgrade kits enable RS-485 or SPI communication for synchronized multi-axis sequencing in automated alignment workflows.
Applications
- Precision alignment of free-space optical paths inside dilution refrigerators and superconducting magnet cryostats
- Nanopositioning of fiber collimators and grating couplers in integrated photonic packaging
- Active stabilization of interferometer arms in gravitational wave detector prototype systems
- Scanning of quantum dot emitters or NV centers under high-field magnetic resonance conditions
- Automated calibration of cryogenic radiometers and bolometric detectors
- Multi-axis nanopositioning platforms for ultra-low-vibration scanning tunneling microscopy (STM)
FAQ
Is the Linear55-x-Pro compatible with liquid helium cooling systems?
Yes — it has been independently tested in both bath-cooled and pumped He-4 systems (1.4–4.2 K) and He-3 cryostats operating below 300 mK. Thermal anchoring via titanium mounting screws is recommended.
What vacuum flange options are available?
Standard configurations include CF-16 and CF-20 knife-edge flanges; custom ConFlat, ISO-KF, or all-metal demountable variants are available upon request.
Can multiple Linear55-x-Pro stages be synchronized for XY or XYZ motion?
Yes — when driven by a common analog reference clock and PID controller, sub-micron inter-stage synchronization is achievable; jitter remains below 50 ns RMS across channels.
Does the resistive position sensor require external excitation?
Yes — a stable 5 V ±0.1% reference supply is required for sensor bridge excitation; output is ratiometric and immune to supply drift.
Is firmware update capability supported?
No — the stage is analog-native and contains no embedded microcontroller; all motion logic resides externally in the host controller, ensuring deterministic timing and long-term maintainability.
