ZOLIX PSAV Series High-Load Motorized Vertical Translation Stage

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 robust vertical displacement under substantial mechanical load. Based on a rigid aluminum alloy base and reinforced lead-screw actuation architecture, the PSAV stage operates on the principle of rotary-to-linear conversion via a high-ratio planetary gearhead (21:2) coupled to a precision-ground trapezoidal lead screw. This configuration ensures high positional stability, minimal axial backlash (<15 µm), and exceptional resistance to torsional deflection during static or quasi-static loading—critical when integrating heavy optics (e.g., monochromators, beam expanders, vacuum chambers, or multi-axis goniometers) into alignment-sensitive optical trains. Unlike standard micrometer-driven or low-torque stepper-based stages, the PSAV series is explicitly rated for central static loads ≥80 kg and verified structural integrity beyond 300 kg—making it suitable for integration into industrial metrology fixtures, synchrotron end-station instrumentation, and high-power laser system platforms where long-term mechanical reliability under sustained load is non-negotiable.

Key Features

• High-load structural design with dual-reinforced mounting flange and thick-section base plate, optimized for load distribution and vibration damping
• Precision-machined 238 × 238 mm top plate (standard); custom dimensions and tapped hole patterns available per ISO 2093 and ANSI/BHMA standards
• Integrated mechanical limit switches at both travel extremes—providing hardware-level over-travel protection compatible with safety interlock circuits
• 57-mm-frame hybrid stepper motor (1.8° step angle, 2.4 A rated current) delivering high holding torque (≥1.2 N·m) without external cooling
• No-load maximum translation speed of 5 mm/s, with programmable acceleration/deceleration profiles via external controller
• Manual override capability via integrated hex-key coupling—enabling precise coarse/fine positioning without power
• Modular interface: Standard M6 threaded mounting holes on base and top plate; optional vacuum-compatible variants (≤10⁻⁶ mbar) available upon request

Sample Compatibility & Compliance

The PSAV stage accommodates optical components, detector assemblies, and optomechanical subassemblies weighing up to 300 kg in static configurations. It complies with ISO 9283 (robotic manipulator performance criteria) for repeatability (±1.5 µm typical over full travel) and meets CE machinery directive 2006/42/EC requirements for mechanical safety. All electrical interfaces conform to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards. The stage is compatible with common motion controllers supporting STEP/DIR signaling (e.g., Newport XPS, Thorlabs K-Cube, or third-party PLC-based systems). For regulated environments, documentation packages—including Factory Acceptance Test (FAT) reports, material traceability sheets, and RoHS/REACH declarations—are provided upon order.

Software & Data Management

While the PSAV stage itself is hardware-only (no embedded firmware or onboard controller), it is fully interoperable with industry-standard motion control ecosystems. Native support includes ASCII command protocols via RS-232/RS-485 and TTL-level STEP/DIR signals. Integration with LabVIEW™, MATLAB® Instrument Control Toolbox, Python (pySerial, PyVISA), and EPICS IOC environments is validated. When deployed in GLP/GMP-aligned laboratories, the stage may be incorporated into audit-trail-capable motion sequences using controllers compliant with FDA 21 CFR Part 11 (electronic records/signatures) — provided the host controller implements appropriate user access controls, event logging, and data integrity safeguards.

Applications

• Vertical height adjustment of heavy spectroscopic instruments (e.g., imaging spectrometers, FTIR interferometers) in calibration laboratories
• Positioning of vacuum-compatible optical tables or cryostat feedthrough mounts in low-temperature physics experiments
• Integration into automated optical inspection (AOI) stations handling large-format semiconductor wafers or display panels
• Alignment platform for high-energy laser delivery optics requiring micron-level vertical reproducibility under thermal drift conditions
• Base-stage for multi-axis nanopositioning systems where coarse Z-motion precedes piezo-driven fine adjustment

FAQ

Is the PSAV stage compatible with vacuum environments?
Yes—vacuum-rated variants with stainless-steel fasteners, low-outgassing lubricants, and sealed motor housings are available (base pressure ≤10⁻⁶ mbar). Specify “VAC” suffix when ordering.
What is the recommended controller for closed-loop operation?
The PSAV does not include encoders; however, it achieves high open-loop repeatability. For closed-loop feedback, we recommend pairing with a controller supporting external linear encoder input (e.g., Aerotech Soloist or Parker Compax3).
Can the top plate be customized with non-standard hole patterns or materials?
Yes—custom machining (e.g., titanium top plates, kinematic mounting features, or fluid-cooling channels) is supported under NDA. Lead time increases by 4–6 weeks.
Does ZOLIX provide OEM integration support?
Yes—ZOLIX offers mechanical CAD models (STEP, IGES), electrical interface schematics, and application engineering consultation for system integrators.
What is the warranty and service policy?
Standard warranty: 24 months parts-and-labor. Extended service contracts including preventive maintenance and recalibration are available globally through authorized ZOLIX partners.
