Overview
The ZOLIX AKSM Series High-Precision Modular Translation Stage is an engineered solution for demanding optical alignment, interferometry, microscopy positioning, and laser beam steering applications. Designed around a rigid aluminum alloy base with hardened stainless steel guide rails and preloaded crossed-roller bearings, the AKSM platform delivers sub-micron repeatability and nanometer-level resolution in unidirectional motion. Its modular architecture supports X-, Y-, Z-, and θ-axis configurations—either as single-axis units or integrated multi-axis stacks—enabling customizable kinematic arrangements without compromising mechanical stability. Motion is actuated via high-torque stepper motors coupled to precision-ground lead screws (pitch: 0.5 mm–1 mm, depending on model), with optional closed-loop feedback via integrated linear encoders (resolution down to 100 nm). The stage operates under ambient laboratory conditions (15–30 °C, <60% RH non-condensing) and is optimized for low-vibration environments typical of optical tables and cleanroom-compatible setups.
Key Features
- Modular design allows flexible X/Y/Z/θ-axis stacking with standardized mounting interfaces (M4/M6 tapped holes, 25 mm grid pattern)
- Repeatability ≤ ±0.5 µm across full travel range (13 mm, 25 mm, and 50 mm variants available)
- Travel accuracy ±2 µm over 25 mm stroke (calibrated per ISO 230-2 Annex B)
- Load capacity up to 5 kg axial (static), 3 kg dynamic (at 10 mm/s max velocity)
- Low-profile construction (height ≤ 32 mm for standard XY configuration) minimizes moment arm effects during multi-stage integration
- Motorized operation compatible with standard RS-232/USB 2.0 interfaces; optional Ethernet (TCP/IP) and TTL trigger I/O for synchronization with cameras or lasers
Sample Compatibility & Compliance
The AKSM series is designed for integration into OEM optical subsystems and research-grade instrumentation. It accommodates standard optical components including mirrors (up to Ø50 mm), lens mounts, fiber couplers, and detector carriers. All structural components comply with RoHS 2011/65/EU directives. Mechanical tolerances adhere to ISO 2768-mK general tolerancing standards. While not certified to specific medical or aerospace standards, the stage’s traceable manufacturing process—including material certification for 6061-T6 aluminum and AISI 440C stainless steel—supports GLP-compliant lab documentation workflows. Mounting surfaces are black anodized (Type II, 15–25 µm thickness) for enhanced scratch resistance and ESD mitigation (surface resistivity <10⁹ Ω/sq).
Software & Data Management
ZOLIX provides the StageMaster™ control suite (v3.2+), a cross-platform application supporting Windows, Linux, and macOS. The software enables script-based motion sequencing (Python API included), real-time position logging (CSV/TXT export), and synchronized multi-axis trajectory planning. All motion commands are timestamped with microsecond resolution and stored with metadata (user ID, session ID, firmware version) to support audit-ready data integrity. For regulated environments, optional firmware upgrade enables 21 CFR Part 11-compliant electronic signatures, audit trail logging (immutable binary records), and role-based access control (Administrator, Operator, Viewer profiles). Communication protocols include SCPI over USB virtual COM port and ASCII command sets compliant with IEEE 488.2.
Applications

- Active stabilization of reference arms in Michelson and Mach–Zehnder interferometers
- Automated focus scanning in confocal and super-resolution microscopy systems
- Beam path correction in ultrafast laser amplifiers and OPCPA pump-probe setups
- Position calibration of photodetector arrays in spectral imaging platforms
- OEM integration into automated wafer inspection tools requiring sub-pixel registration accuracy
FAQ
What is the maximum bidirectional repeatability specification for the AKSM-25XY model?
Bidirectional repeatability is ≤ ±0.7 µm (95% confidence, 50 measurements per direction) when operated at 20 °C ±1 °C with 24-hour thermal soak.
Can the AKSM stage be used in vacuum environments?
Standard models are rated for ambient air only. Vacuum-compatible variants (AKSM-V series) are available with dry-lubricated bearings, vented motor housings, and outgassing-tested adhesives (per ASTM E595).
Is third-party controller compatibility supported?
Yes—StageMaster™ exposes a documented ASCII command set. Common integrations include Thorlabs APT, Newport ESP301, and LabVIEW via VISA or DLL wrappers.
How is thermal drift compensated during long-duration scans?
No active thermal compensation is built-in; however, the low coefficient of thermal expansion (CTE ≈ 23.6 × 10⁻⁶ /°C for 6061-T6) and symmetrical thermal mass distribution minimize gradient-induced hysteresis. Users may implement external temperature feedback loops using the analog input port.
What maintenance intervals are recommended for optimal performance?
Lubrication reapplication is advised every 12 months or after 5,000 km of cumulative travel. Linear encoder calibration should be verified annually using a traceable laser interferometer (e.g., Keysight 5530 system).
