ZOLIX uFS20-60 High-Precision Motorized Linear Translation Stage

Overview

The ZOLIX uFS20-60 is a compact, high-precision motorized linear translation stage engineered for demanding optical alignment, interferometry, micro-positioning, and automated laboratory instrumentation applications. Designed around a rigid hard-anodized aluminum alloy body (60 × 60 mm top plate, 20 mm travel), the stage integrates a C3-grade imported ball screw (Φ6 mm, 1 mm lead) and preloaded crossed roller bearings to deliver sub-micron motion fidelity under dynamic loading conditions. Its kinematic architecture follows classical precision mechanical principles: the ball screw converts rotary motion from a five-phase stepper motor into highly repeatable linear displacement, while the crossed roller guide system ensures minimal parasitic motion—controlling pitch, yaw, straightness, and parallelism within tight metrological tolerances. The stage operates in open-loop mode but supports closed-loop integration via external encoders; its mechanical design inherently minimizes thermal drift and hysteresis, making it suitable for environments requiring long-term positional stability without active feedback.

Key Features

• Structural integrity: 6061-T6 aluminum body with matte black anodized finish (hardness ≥ 60 HV), providing corrosion resistance, dimensional stability, and ESD-safe surface properties.
• Guidance performance: Imported crossed roller linear bearings with integrated preload ensure load capacity up to 6 kg (horizontal), 3 kg (vertical/inverted), and maintain ≤ 5 µm straightness and ≤ 0.05 mm static parallelism over full stroke.
• Motion resolution and accuracy: With a 0.36° five-phase stepper motor (Oriental Motor PK523HPMB) and compatible 20× microstepping driver (e.g., CVD512BR-K), the stage achieves effective resolution down to 0.05 µm — validated across >90% of units per factory test reports.
• Positional fidelity: Unidirectional positioning accuracy ≤ 10 µm, bidirectional repeatability ≤ ±1 µm, and backlash ≤ 1 µm meet ISO 230-2:2014 test protocols for linear motion systems.
• Integrated sensing: Dual OMRON EE-SX4320 slot-type photoelectric limit switches and one home sensor enable deterministic homing and end-of-travel protection with NPN open-collector output (5–24 VDC, ≤ 8 mA).
• Interoperability: Standard 10-pin LEMO-compatible connector, 0.2 m shielded motion cable, and compliance with common industrial motion control voltage and logic standards simplify integration into OEM systems or LabVIEW/Python-controlled setups.

Sample Compatibility & Compliance

The uFS20-60 is optimized for mounting optical components such as mirrors, beam splitters, fiber couplers, and detector mounts with M3 or M4 threaded holes. Its low mass (0.58 kg), compact footprint, and minimal out-of-plane motion errors (<20 arcsec pitch/yaw) make it compatible with vibration-sensitive configurations—including optical tables with passive or active damping, cleanroom-class optical benches (ISO Class 5–7), and vacuum-compatible adaptations (when sealed per customer specification). While not certified to UL/CE for standalone safety, the stage complies with RoHS 2011/65/EU and REACH (EC 1907/2006) material restrictions. Mechanical specifications align with ISO 10110-7 (optical component mounting interfaces) and are routinely referenced in alignment procedures compliant with ISO/IEC 17025:2017 for calibration laboratories.

Software & Data Management

The uFS20-60 operates as a hardware-level positioning module and does not include embedded firmware or onboard controllers. It requires external motion drivers (e.g., Oriental Motor CVD512BR-K) and host-based control software. Native compatibility includes National Instruments LabVIEW (via NI Motion API), MATLAB Instrument Control Toolbox, Python (using PySerial or vendor-specific SDKs), and common PLC platforms supporting pulse/direction signaling. All position commands follow standard STEP/DIR TTL-level protocol with configurable acceleration profiles. Audit trails, parameter logging, and motion sequence replay are managed entirely at the host system level—enabling full traceability in GLP/GMP-regulated workflows when paired with 21 CFR Part 11-compliant software environments.

Applications

• Precision optical path length adjustment in Michelson and Mach-Zehnder interferometers
• Automated focus scanning in confocal microscopy and laser scanning cytometry
• Multi-axis alignment of free-space quantum optics components (e.g., waveplates, polarizers, single-photon detectors)
• Calibration stage for optical encoders, autocollimators, and laser Doppler vibrometers
• Component indexing in automated spectrometer slit mechanisms and monochromator tuning assemblies
• Micro-manipulation support in Raman spectroscopy sample positioning systems

FAQ

Is the uFS20-60 compatible with vacuum environments?

Standard units are rated for ambient air operation only; vacuum-compatible variants require custom sealing, lubricant substitution (e.g., dry-film MoS₂), and non-outgassing anodization—available upon request with lead-time extension.
What is the recommended driver for achieving 0.05 µm resolution?

The Oriental Motor CVD512BR-K microstepping driver is factory-validated for 20× subdivision and optimal current regulation (0.75 A RMS) with the PK523HPMB motor.
Can multiple uFS stages be synchronized in a multi-axis system?

Yes—using a centralized motion controller supporting simultaneous STEP/DIR output and shared enable/limit lines, synchronization jitter remains below 100 ns across axes when cabled per EMC best practices.
Does ZOLIX provide calibration certificates with traceability to NIST or CNAS?

Factory calibration reports (including repeatability, backlash, and straightness data) are provided with each unit; accredited calibration per ISO/IEC 17025 is available as an optional service through ZOLIX’s Beijing metrology lab.
What maintenance is required over the product lifetime?

No scheduled maintenance is required under normal lab-use conditions; periodic inspection of coupling integrity and visual verification of guide rail cleanliness is advised every 12 months or after 10,000 motion cycles.
