OWIS MVT30-Z Manual Precision Translation Stage

Overview

The OWIS MVT30-Z Manual Precision Translation Stage is a high-stiffness, low-hysteresis linear positioning system engineered for sub-micron repeatability in demanding optical laboratory environments. Based on OWIS’ proprietary precision-ground stainless steel lead screw and hardened bronze nut architecture, the stage operates via fine-pitch micrometer adjustment (1 µm sensitivity per graduation), delivering deterministic mechanical displacement without reliance on electronic feedback or motorized actuation. Its core function is to enable stable, drift-free, and vibration-insensitive axial translation of optical components—including mirrors, lenses, fiber couplers, and detectors—within interferometric setups, laser cavity alignment stations, and metrology-grade optical benches. Designed and manufactured in Germany, the MVT30-Z adheres to stringent dimensional stability requirements under thermal gradients (coefficient of linear expansion: 23.1 × 10⁻⁶ K⁻¹ for 6061-T6 aluminum housing), ensuring long-term positional fidelity across ambient lab conditions (15–30 °C). The stage integrates seamlessly into modular OWIS optical mounting ecosystems, supporting both vertical (Z-axis) and horizontal (X/Y) configuration via standardized M4 and M6 tapped holes.

Key Features

• Precision micrometer-driven translation with 1 µm minimum incremental movement and < ±0.5 µm bidirectional repeatability under 50 N axial load
• Self-locking mechanical design eliminates need for external braking; position retention maintained without power or manual clamping
• Black anodized 6061-T6 aluminum body provides corrosion resistance, non-magnetic compatibility (relative permeability µᵣ ≈ 1.0), and ESD-safe surface (surface resistivity: 10⁶–10⁹ Ω/sq)
• Modular mounting interface: compatible with OWIS linear slides (e.g., LMS series), kinematic pins (Ø3 mm, Ø6 mm), and standard optical breadboard patterns (M6 or ¼”-20)
• Two load-class variants: Standard (130 N static load, 2.5 N·m tilt moment) and High-Capacity (200 N static load, 4 N·m tilt moment), both rated for continuous operation at ≤80% of maximum specified load
• Optimized mass-to-rigidity ratio: 0.82 kg unit mass with first-mode resonance frequency >180 Hz (measured on granite base), minimizing coupling with low-frequency lab vibrations

Sample Compatibility & Compliance

The MVT30-Z is qualified for use with optomechanical components weighing up to 20 kg when paired with appropriate support structures (e.g., OWIS HCS column mounts or rigid optical tables). It maintains mechanical integrity under vacuum conditions down to 10⁻⁴ mbar (non-outgassing anodization, no lubricants exposed to chamber interior). All materials comply with RoHS 2011/65/EU and REACH Annex XVII restrictions. While not certified to ISO 9001 as a standalone component, the stage is produced within OWIS’ ISO 9001:2015-certified manufacturing facility and conforms to dimensional tolerances referenced in DIN ISO 2768-mK (medium class for linear dimensions). For GLP/GMP-aligned laboratories, the stage supports traceable calibration via third-party metrology labs using laser interferometry (e.g., Keysight 5530 or Renishaw XL-80 systems), and its mechanical hysteresis profile is documented per ISO 230-2 Annex C for manual positioning devices.

Software & Data Management

As a purely manual mechanical stage, the MVT30-Z requires no firmware, drivers, or software integration. However, it is fully interoperable with OWIS’ digital calibration and alignment documentation ecosystem: users may log positional settings, environmental conditions (temperature, humidity), and verification timestamps in OWIS’ optional TraceLog™ spreadsheet template—a tool structured to satisfy audit requirements under FDA 21 CFR Part 11 (electronic records/electronic signatures) when used with controlled-access shared drives and versioned Excel workbooks. Positional history can be cross-referenced with interferometric alignment reports generated by compatible measurement systems (e.g., Zygo Verifire™ or 4D Technology AccuFiz™), enabling full chain-of-custody documentation for ISO/IEC 17025 accreditation.

Applications

• Laser beam steering and cavity length tuning in Ti:sapphire and fiber laser resonators
• Active/passive alignment of free-space optical interconnects in photonic integrated circuit (PIC) packaging
• Reference mirror positioning in Michelson and Mach–Zehnder interferometers for nanometer-level path-length control
• Coarse/fine focusing stages in confocal microscopy and optical coherence tomography (OCT) source alignment
• Thermal drift compensation in ultra-stable optical delay lines (ODLs) used in quantum optics experiments
• Component staging in automated optical inspection (AOI) test fixtures where EMI immunity and zero electromagnetic emission are mandatory

FAQ

Is the MVT30-Z compatible with vacuum environments?

Yes—when specified with vacuum-compatible assembly (no grease on lead screw, dry-film solid lubricant option), it operates continuously at pressures down to 10⁻⁴ mbar.
Can multiple MVT30-Z stages be stacked for multi-axis motion?

Yes—OWIS provides orthogonal mounting brackets (e.g., ZB-30) and kinematic base plates (KB-50) to construct XYZ stacks with angular misalignment < 5 arcsec per interface.
What is the recommended recalibration interval?

No periodic recalibration is required for mechanical performance; however, users conducting ISO/IEC 17025-compliant measurements should verify displacement accuracy annually using a calibrated laser interferometer.
Does OWIS provide traceable calibration certificates?

Yes—upon request, OWIS issues manufacturer’s calibration reports (traceable to PTB via DAkkS-accredited labs) documenting hysteresis, repeatability, and linearity over full travel range.
Are replacement micrometer knobs or lead screws available as spare parts?

Yes—all mechanical subassemblies—including M4 × 0.7 pitch lead screws, bronze nuts, and ergonomic knurled knobs—are stocked and orderable under OWIS part numbers MVT30-Z-KNOB and MVT30-Z-SCREW.
