Overview
The ZOLIX PSAV Series High-Load Motorized Vertical Translation Stage is an engineered precision motion solution designed for demanding optical and photonics laboratory applications requiring stable vertical displacement under substantial mechanical load. Built upon a robust aluminum alloy frame with hardened stainless-steel lead screws and preloaded linear guides, the PSAV stage operates on a high-torque stepper motor drive system coupled with a 21:2 planetary gearhead—ensuring high positional repeatability (< ±1.5 µm), low backlash (< 10 arcsec), and smooth, vibration-damped vertical translation. Unlike standard micrometer-driven or low-torque motorized stages, the PSAV series is specifically optimized for static and quasi-static positioning of heavy optical components—including large mirrors, beam combiners, vacuum-compatible optical mounts, and multi-axis optomechanical assemblies—where gravitational sag, thermal drift, and dynamic stability are critical performance constraints.
Key Features
- High-load vertical translation capability: Rated center-load capacity ≥80 kg; scalable up to 300 kg via motor and gearbox configuration per application requirements
- Precision-engineered mechanical architecture: Dual linear rail guidance with anti-rotation constraint and integrated preload eliminates wobble and pitch/yaw deviation during lift
- Integrated limit switches (top/bottom) with hardware-level emergency stop functionality compliant with IEC 61800-5-2 safety standards
- Standard 1.8° hybrid stepper motor (57 N·cm holding torque, 2.4 A rated current) with microstepping support (1/8 to 1/32 step resolution via external driver)
- Modular platform interface: 238 × 238 mm top plate with M6 tapped holes on 25 mm grid; customizable mounting patterns and surface finishes (e.g., black anodized, vacuum-compatible dry film lubrication)
- Direct-drive compatibility: Optional encoder feedback integration (1000-line quadrature) available for closed-loop position verification in GLP/GMP-aligned setups
Sample Compatibility & Compliance
The PSAV stage supports broad compatibility with standard optical breadboards (e.g., Thorlabs, Newport), kinematic mirror mounts, and custom vacuum chambers (up to 10⁻⁶ mbar with optional sealing kits). Its structural rigidity (static deflection < 1.2 µm at 80 kg center load) ensures minimal optical path deviation during repositioning—critical for interferometric alignment, laser cavity optimization, and synchrotron beamline instrumentation. The device conforms to CE marking requirements (EMC Directive 2014/30/EU, Machinery Directive 2006/42/EC) and meets RoHS 3 compliance for restricted substances. All electrical interfaces adhere to SELV (Safety Extra-Low Voltage) design principles per IEC 61000-6-2/6-4.
Software & Data Management
The PSAV series is compatible with industry-standard motion control ecosystems including ZOLIX’s proprietary ZMotion SDK (C/C++, Python, LabVIEW APIs), as well as third-party platforms such as National Instruments Motion Control, MATLAB Instrument Control Toolbox, and EPICS IOC drivers. Position logs, motor current telemetry, and switch status timestamps are exportable in CSV/JSON format with configurable sampling intervals (10–1000 Hz). Audit trails—including user-initiated moves, firmware updates, and error events—are retained locally with ISO/IEC 17025-aligned timestamping and SHA-256 integrity hashing for traceability in regulated environments (e.g., ISO 17025-accredited calibration labs).
Applications
- Vertical alignment of high-mass optics in ultrafast laser systems and EUV lithography testbeds
- Height adjustment of sample stages in confocal Raman and photoluminescence spectroscopy setups
- Positioning backbone for automated optical switching matrices in fiber-optic quantum communication test stations
- Integration into multi-axis goniometers for X-ray diffraction (XRD) and small-angle X-ray scattering (SAXS) beamlines
- Stable elevation platform for cryogenic optical mounts operating at 4 K–77 K (with optional low-outgassing materials)
FAQ
What is the maximum repeatable positioning accuracy under full rated load?
Under 80 kg center load and ambient temperature (23 ± 1 °C), bidirectional repeatability is ≤ ±1.5 µm over full travel, verified per ISO 230-2 Annex B protocols.
Can the PSAV stage be operated in vacuum environments?
Yes—vacuum-rated variants (PSAV-VAC) are available with stainless-steel construction, vacuum-compatible lubricants, and vented motor housings; certified for operation down to 10⁻⁶ mbar.
Is encoder feedback supported natively?
Encoder integration is optional and requires external controller configuration; ZOLIX provides mechanical mounting provisions and signal routing paths for incremental or absolute encoders.
What power supply specifications are required?
Standard operation uses a 24–48 VDC regulated supply with peak current capability ≥5 A; ripple must remain below 150 mVpp to maintain microstepping fidelity.
Does the stage support TTL-triggered motion commands?
Yes—digital input lines accept 5 V TTL pulses for jog, home, or preset-position triggering, synchronized to internal motion profiles with sub-millisecond latency.
