ZOLIX PSAxxx-11-Z Series Precision Motorized Translation Stage

Overview

The ZOLIX PSAxxx-11-Z Series Precision Motorized Translation Stage is an engineered solution for high-repeatability linear positioning in optical alignment, interferometry, spectroscopic scanning, and automated microscopy applications. Based on a robust mechanical architecture featuring ground ball screws (C5 grade or better), preloaded linear motion rails, and low-backlash elastic couplings, the stage delivers sub-micron repeatability (≤ ±0.5 µm) and long-term positional stability under continuous operation. Its core actuation relies on open-loop stepper motor control—optimized for deterministic step resolution without encoder feedback—while maintaining compatibility with closed-loop upgrades via optional encoder kits. The stage operates within ambient laboratory conditions (15–30 °C, <60% RH non-condensing) and is designed for integration into vacuum-compatible enclosures (with optional stainless-steel hardware and fluoropolymer-coated components). All structural components—including base plate, carriage, and mounting brackets—are CNC-machined from stress-relieved aluminum alloy 6061-T6 to ensure dimensional fidelity and thermal homogeneity across temperature gradients.

Key Features

• Integrated RS232 interface enabling direct serial communication with SC300 and MC-series motion controllers—supporting ASCII command protocol for position, velocity, acceleration, and I/O status queries.
• Factory-calibrated end-of-travel and home-position optical limit switches provide hardware-level motion boundary enforcement and absolute referencing—critical for multi-axis synchronization and system boot-up initialization.
• Standardized M4 and M6 tapped hole patterns (per ISO 841 and DIN 7162) allow rigid, repeatable stacking with orthogonal stages, rotation mounts, and kinematic platforms—enabling rapid assembly of XYZ, XYZθ, or XYZθφ configurations.
• Dedicated right-angle bracket design ensures angular deviation ≤ 15 arcseconds between mating axes—verified via autocollimator traceable to NIM (National Institute of Metrology, China) standards.
• Power-loss safety circuit engages electromagnetic braking upon mains interruption, preventing uncontrolled drift or gravitational slippage during unexpected shutdown—essential for vertical or inclined installations.
• Modular drive train accommodates optional gearmotor integration for increased torque output and reduced speed (e.g., for high-inertia loads >10 kg), preserving mechanical integrity without redesigning the stage frame.

Sample Compatibility & Compliance

The PSAxxx-11-Z series is compatible with standard optical payloads including lens holders, fiber launchers, mirror mounts, and detector sleds weighing up to 10 kg (model-dependent). It meets mechanical interface requirements specified in ISO 10110-7 (optical component mounting) and supports alignment workflows compliant with ISO/IEC 17025 calibration laboratory practices. When paired with SC300 controllers running firmware v3.2+, the system supports basic audit trail logging (timestamped command history), aligning with GLP documentation expectations. While not intrinsically rated for hazardous environments, optional IP54-rated enclosure kits are available for dust- and splash-resistant deployment in shared instrument rooms.

Software & Data Management

Native control is achieved through ZOLIX’s MotionMaster™ GUI (Windows 10/11, 64-bit), offering point-to-point move sequencing, jog mode, macro scripting (TCL-based), and real-time position monitoring. For OEM integration, a documented DLL API and Python-compatible wrapper library enable embedding into LabVIEW, MATLAB, or custom C++ applications. All controller firmware adheres to RS232 electrical specifications per EIA/TIA-232-F, ensuring interoperability with third-party DAQ systems. Data export supports CSV and HDF5 formats—facilitating traceable post-processing in compliance with ISO/IEC 17025 Clause 7.7 (results reporting).

Applications

• Optical path length adjustment in Michelson and Mach–Zehnder interferometers
• Automated wavelength calibration of monochromators and tunable lasers
• Sample raster scanning in confocal Raman and fluorescence lifetime imaging (FLIM)
• Active alignment of free-space optical interconnects in photonic packaging
• Position-critical beam steering in ultrafast pump-probe setups
• Multi-axis coordination in automated ellipsometry and reflectometry stations

FAQ

Is encoder feedback available as a factory option?
Yes—high-resolution optical encoders (1 µm resolution, quadrature output) can be integrated at time of order for closed-loop verification; however, the base configuration operates in open-loop stepper mode.
Can the stage be used in vacuum environments?
Standard units are air-rated; vacuum-compatible variants (10⁻⁵ mbar) require optional stainless-steel construction, dry-lubricated bearings, and vented motor housings—contact technical sales for configuration codes.
What is the typical bidirectional repeatability specification?
Measured per ISO 230-2 Annex B: ≤ ±0.5 µm over full travel range, verified at 23 ± 1 °C after 30-minute thermal soak.
Are custom travel ranges supported beyond the listed models?
Yes—custom stroke lengths from 25 mm to 500 mm are available under OEM agreement; lead time and minimum order quantities apply.
Does the RS232 interface support hardware flow control?
No—only software (XON/XOFF) flow control is implemented; for high-throughput streaming, use the optional USB-to-RS232 adapter with buffered FIFO.
