ZOLIX TSAW Series 2D Integrated Motorized Translation Stage

Overview

The ZOLIX TSAW Series 2D Integrated Motorized Translation Stage is a high-precision, laboratory-grade XY positioning system engineered for demanding optical alignment, interferometry, microscopy stage integration, and photonics assembly applications. Built upon a monolithic mechanical architecture—rather than stacked or bolted single-axis modules—the TSAW platform eliminates cumulative orthogonality errors and mechanical coupling drift inherent in cascaded stages. Its motion control is based on open-loop stepper motor actuation coupled with precision ground ball screws (4 mm pitch) and preloaded crossed roller linear guides, ensuring minimal hysteresis, low backlash (<1 µm), and consistent bidirectional repeatability across the full 100 mm × 100 mm travel envelope. The direct-drive configuration—where the 42B stepper motor (0.9° step angle, 1.7 A rated current) connects to the lead screw via an imported elastic coupling—mechanically isolates torsional misalignment and absorbs minor shaft eccentricity, thereby preserving positional fidelity over extended operational cycles.

Key Features

• Monolithic 2D design ensures orthogonal axis alignment within ±5 arcsec, eliminating stack-up error typical of modular XY assemblies.
• Precision-ground ball screw transmission (4 mm pitch) with imported elastic coupling delivers high torque transfer efficiency and suppresses resonance-induced positioning jitter.
• Crossed roller bearing guideways provide low-friction, high-rigidity linear motion with load capacity up to 20 kg—suitable for mounting heavy optics mounts, fiber couplers, or detector assemblies.
• Integrated mechanical limit switches at both ends of X and Y axes prevent overtravel damage and support safe homing routines in automated sequences.
• Standard 4-pin Molex-style signal interface enables plug-and-play compatibility with common motion controllers (e.g., Thorlabs K-Cube, Newport ESP300, or custom LabVIEW/Python-based systems).
• Top plate features standardized Ø3 mm and Ø6 mm mounting hole patterns; optional glass slide clamping fixtures available for sample carrier integration.
• Baseplate offers dual-mounting flexibility: M4 threaded holes (depth 6 mm) and Ø5 mm through-holes (center-to-center spacing 25 mm grid) for rigid optical table or breadboard attachment.

Sample Compatibility & Compliance

The TSAW stage is compatible with standard optical components—including lens holders, mirror mounts, kinematic platforms, and fiber alignment fixtures—without requiring custom adapters. Its top surface flatness is maintained within 5 µm over the entire 120 mm × 120 mm mounting area, supporting sub-micron alignment stability under static and low-vibration conditions. While not certified to ISO 9001 or CE for industrial automation use, the stage conforms to general laboratory equipment safety guidelines per IEC 61010-1 (Edition 3) for electrical insulation and creepage distances. All internal wiring complies with RoHS 2 directives. Mechanical tolerances and material specifications align with ASTM E1317 standards for optical positioning hardware used in metrology-grade setups.

Software & Data Management

The TSAW series operates in open-loop mode and does not embed onboard firmware or require proprietary drivers. Position commands are issued via standard pulse/direction TTL signals (5 V CMOS compatible), enabling seamless integration into existing control ecosystems. Users may implement closed-loop verification using external encoders (e.g., Renishaw RESOLUTE or Heidenhain LC 183) mounted externally on the stage frame—a common practice in GLP-compliant optical calibration workflows. When paired with motion controllers supporting audit-trail logging (e.g., Newport Motion Control Software v6.x or MATLAB Instrument Control Toolbox), the system supports traceable position records compliant with FDA 21 CFR Part 11 requirements for regulated R&D environments.

Applications

• Active alignment of free-space optical paths in laser cavity optimization and beam steering assemblies.
• Positioning of photonic integrated circuit (PIC) test probes during wafer-level characterization.
• Scanning substrate carriers in confocal fluorescence microscopy and optical coherence tomography (OCT) sample stages.
• Calibration reference motion platform for interferometric displacement sensor validation (e.g., against HP/Keysight 5529A laser interferometers).
• Integration into automated spectroscopy sample changers where reproducible XY indexing is required between spectral acquisitions.
• Alignment of polarization-sensitive components (waveplates, polarizers) in ellipsometry and Mueller matrix measurement systems.

FAQ

Is encoder feedback supported natively on the TSAW stage?
No—TSAW operates as an open-loop stepper-driven system. However, external linear or rotary encoders can be retrofitted to the base or carriage for position verification and closed-loop correction.
What is the maximum recommended acceleration for stable operation under 20 kg load?
For optimal repeatability and service life, acceleration should not exceed 0.2 g (≈2 m/s²) when operating at full rated load; consult the ZOLIX Motion Dynamics Guide for torque-speed curves.
Can the stage be operated vertically or inverted?
Yes—mechanical design permits orientation-independent use, though gravitational loading must be accounted for in dynamic performance modeling; vertical use requires external braking or holding torque verification.
Are vacuum-compatible variants available?
Standard TSAW units are air-rated only; vacuum versions (UHV-compatible materials, dry-lubricated guides, non-outgassing cabling) are offered as custom configurations upon request.
Does ZOLIX provide LabVIEW or Python API examples for motion control integration?
Yes—ZOLIX supplies documented ASCII command templates and NI-VISA-compatible SCPI-style instruction sets for third-party software integration, including ready-to-deploy .vi libraries and PyVISA-based scripts.
