Auniontech XWS Series XY Piezo Motor Translation Stage with CrossFixx™ Drive

Overview

The Auniontech XWS Series XY Piezo Motor Translation Stage is an ultra-compact, high-dynamics motion platform engineered for precision optical positioning in demanding laboratory and OEM instrumentation environments. Unlike conventional stepper or servo-driven stages, the XWS leverages Xeryon’s proprietary CrossFixx™ ultrasonic piezoelectric motor technology — a friction-driven, resonant-mode actuation principle that delivers nanometer-scale resolution without mechanical reduction gears, lead screws, or magnetic interference. This architecture enables simultaneous high speed (up to 250 mm/s), sub-50 nm closed-loop repeatability, and zero-power position retention via passive mechanical locking — critical for vibration-sensitive applications such as confocal microscopy, automated wafer inspection, and adaptive optics alignment. The stage integrates seamlessly into space-constrained optical breadboards (M6-compatible), microscope frames, and custom optomechanical assemblies, supporting both stand-alone operation and embedded system integration.

Key Features

• High-Dynamics XY Motion: 100 × 100 mm travel range with bidirectional repeatability ≤ ±50 nm (with optional encoder feedback); maximum velocity of 250 mm/s ensures rapid field-of-view scanning without settling delay.
• Ultra-Low Profile Design: Total height under 25 mm facilitates integration beneath objective lenses, within compact imaging enclosures, or stacked multi-axis configurations.
• Passive Power-Off Locking: Mechanical self-locking based on static friction eliminates drift during power interruption — essential for GLP/GMP-compliant metrology workflows and fail-safe optical path control.
• Robust Environmental Performance: Rated for continuous operation from −40 °C to +70 °C; qualified for 10 g RMS vibration and 100 g shock (per IEC 60068-2-6/27), enabling deployment in industrial machine vision systems and aerospace-qualified payloads.
• Modular Interfacing: Standard analog ±10 V input with optional digital protocols (USB, RS-485, CANopen) supports compatibility with LabVIEW, MATLAB, Python-based automation frameworks, and PLC-controlled production lines.
• OEM-Ready Scalability: Available as bare motor modules (CrossFixx™ core), fully assembled stages, or co-engineered subsystems — including custom aperture cutouts, kinematic mounting interfaces, and integrated shutter coupling.

Sample Compatibility & Compliance

The XWS stage accommodates standard 25 mm × 75 mm microscope slides, 1-inch optical mounts, and custom substrates up to 3 kg mass. Its non-magnetic stainless-steel and aluminum alloy construction ensures compatibility with SEM/TEM sample chambers and MRI-adjacent setups. All units comply with CE marking requirements (2014/30/EU EMC Directive, 2014/35/EU LVD), RoHS 2011/65/EU, and ISO 9001:2015 quality management standards at the manufacturer level. For regulated environments, the stage supports audit-ready motion logging when paired with compliant controllers meeting FDA 21 CFR Part 11 data integrity criteria (electronic signatures, audit trails, and user access controls).

Software & Data Management

Auniontech provides native drivers for Windows/Linux platforms, including DLLs, .NET wrappers, and Python APIs. Motion profiles (trapezoidal, S-curve, point-to-point) are programmable via ASCII command sets over serial or USB. Real-time position feedback (optional capacitive or optical encoder) enables closed-loop trajectory validation with timestamped CSV export. Firmware updates preserve backward compatibility, and configuration parameters — including drive voltage, resonance frequency tuning, and stall detection thresholds — remain field-adjustable without hardware modification. Integration with third-party platforms (e.g., Thorlabs Kinesis, Newport Motion Control Software) is supported through standardized SCPI-like syntax.

Applications

• Automated fluorescence microscopy stage scanning and tile-based image stitching
• High-throughput semiconductor wafer defect mapping with sub-micron registration accuracy
• Dynamic laser beam steering calibration in free-space optical interconnect testbenches
• Real-time focus correction in adaptive optics systems using wavefront sensor feedback
• Compact optical shutter modules for pulsed laser synchronization (Q-switch gating, pump-probe timing)
• OEM integration into portable Raman spectrometers, OCT endoscopic probes, and handheld LIBS analyzers

FAQ

Does the XWS stage require active cooling or forced ventilation?

No — the CrossFixx™ motor operates at ultrasonic frequencies (>120 kHz) with minimal resistive heating; convection cooling suffices across its full operating temperature range.
Can the stage be used in vacuum environments?

Standard units are rated for ambient air only; vacuum-compatible variants (with outgassing-certified materials and dry-lubricated guides) are available upon engineering review.
What shutter synchronization latency can be expected when triggering externally?

End-to-end electrical-to-mechanical latency is < 80 µs (measured from TTL edge to shutter blade motion onset) with proper cabling and impedance matching.
Is encoder feedback included by default?

Encoder integration is optional; high-resolution capacitive sensors (5 nm resolution) or incremental optical encoders (100 nm resolution) may be factory-installed per application requirements.
Do you support custom firmware development for proprietary control logic?

Yes — Xeryon provides SDK access and joint firmware co-development under NDA for Tier-1 OEM partners integrating the CrossFixx™ motor core into proprietary motion subsystems.
