Overview
The ZOLIX PSAxxx-11-X Series Precision Motorized Translation Stage is an engineered solution for high-stability, repeatable linear motion in optical alignment, interferometry, spectroscopy, and micro-positioning applications. Based on Couette-type mechanical architecture—comprising a ground ball screw drive coupled with preloaded linear carriage rails—the stage delivers deterministic displacement with minimal elastic hysteresis and thermal drift. Its monolithic base structure is fabricated from aerospace-grade aluminum alloy (6061-T6), subjected to stress-relief annealing and precision surface grinding to ensure dimensional stability across ambient temperature fluctuations (±0.5 °C). Each unit undergoes full-travel metrological verification using laser interferometry (ISO 230-2 compliant methodology), confirming straightness ≤10 µm and flatness ≤15 µm per 100 mm of travel—performance metrics aligned with ISO 10360-2 specifications for coordinate measuring machine (CMM) staging subsystems.
Key Features
- Ground ball screw transmission with pitch options of 4 mm or 5 mm, enabling sub-micron resolution when paired with 8-step microstepping drivers
- Imported linear motion carriages with hardened steel raceways and recirculating ball bearings, optimized for low friction coefficient (<0.005) and long-term wear resistance
- Integrated dual mechanical end-stop switches and one optical home sensor (NPN output, 5 V TTL compatible) for hardware-level position safeguarding and automated homing routines
- Rear-mounted calibrated micrometer handwheel (0.01 mm graduation) allowing manual fine adjustment without motor disengagement—critical for alignment-sensitive setups such as cavity length tuning in lasers
- Standard DB9 male interface supporting direct integration with ZOLIX’s KDC, KMC, or third-party motion controllers compliant with RS-422 or step/direction protocols
- Modular mounting footprint conforming to ANSI/EIA-310-D standard hole patterns (M4 and M6 tapped holes), facilitating multi-axis orthogonal or stacked configurations
Sample Compatibility & Compliance
The PSAxxx-11-X series is designed for use with optomechanical payloads including mirrors, beam splitters, fiber collimators, and detector mounts—supporting centered static loads up to 70 kg depending on model length. All units comply with CE marking requirements under the Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. Mechanical tolerances adhere to ISO 2768-mK general tolerancing standards; surface finish meets ISO 1302 Ra ≤0.8 µm on critical rail contact surfaces. The anodized coating (Type II, 15–20 µm thickness) satisfies MIL-A-8625F Class 2 corrosion resistance requirements for laboratory environments.
Software & Data Management
ZOLIX provides native driver support for Windows-based platforms via DLL libraries and LabVIEW VIs, enabling seamless integration into custom automation sequences. Firmware supports non-volatile memory storage of user-defined zero offset, acceleration profiles, and jog parameters—ensuring reproducible startup conditions across sessions. Audit trails for motion commands are recordable through external DAQ systems interfaced via TTL trigger outputs. While the stage itself does not embed firmware-level audit logging, its deterministic response enables full traceability when used within GLP/GMP-compliant workflows governed by FDA 21 CFR Part 11–validated controller software.
Applications
- Precision optical path length adjustment in Michelson and Mach-Zehnder interferometers
- Automated sample scanning in Raman, FTIR, and fluorescence microscopy stages
- Beam steering calibration in free-space quantum optics experiments
- Wafer-level alignment during photolithography mask registration
- Dynamic focus correction in adaptive optics test benches
- Multi-axis nanopositioning integration (X-Y-Z or X-θ configurations) using standardized kinematic mounts
FAQ
What is the maximum recommended payload for vertical orientation?
For vertical mounting (motor-down configuration), the maximum centered load is reduced to 30 kg to maintain backlash and lifetime specifications.
Can this stage be operated in vacuum environments?
Standard units are rated for ambient air only; vacuum-compatible variants (with dry-lubricated screws and outgassing-certified materials) are available upon request under custom order code PSAxxx-11-X-VAC.
Is encoder feedback supported?
The base model uses open-loop stepper control; closed-loop operation with incremental optical encoders (1 µm resolution) is supported via optional upgrade kits and compatible ZOLIX servo controllers.
How is thermal expansion compensated over extended travel ranges?
No active compensation is built-in; however, the aluminum base’s CTE (23.6 × 10⁻⁶ /°C) is documented in the technical datasheet to enable software-based thermal drift modeling in mission-critical applications.
Are CAD models and mounting templates provided?
Yes—STEP and IGES files, along with DXF mounting templates and tolerance stack-up diagrams, are included in the download package after product registration on the ZOLIX international portal.
