ZOLIX NFP-3561 / NFP-3561L Ultra-Precision Manual 3-Axis Translation Stage

Overview

The ZOLIX NFP-3561 and NFP-3561L are monolithic, ultra-precision manual translation stages engineered for sub-micron positional stability and repeatability in demanding optical alignment applications. Designed around a rigid, one-piece stainless steel body—electropolished and matte-finished to minimize particulate generation and outgassing—the stage integrates imported high-precision crossed roller bearings with ZOLIX’s proprietary precision grinding process. This architecture eliminates mechanical hysteresis and elastic deformation commonly observed in bolted or modular stage assemblies, enabling true 1 µm resolution in manual positioning without stick-slip or backlash. The stages operate on the principle of direct micrometer-driven linear displacement, where fine-pitch screws translate rotational input into highly controlled, deterministic linear motion. Unlike motorized or piezo-based alternatives, this purely mechanical design ensures zero electromagnetic interference (EMI), intrinsic thermal stability, and full compatibility with ultra-high vacuum (UHV) environments up to 10⁻⁷ mbar and ISO Class 4 (Class 10) cleanrooms.

Key Features

• Monolithic stainless steel construction with matte electropolished surface—optimized for low outgassing, corrosion resistance, and particulate control in vacuum and cleanroom settings.
• Imported crossed roller bearing guideways with preloaded contact geometry—delivering straightness deviation < 2 µm over 25 mm travel and angular deviation < 5 arcsec (pitch/yaw).
• Micrometer-driven actuation with 1 µm minimum incremental movement and ≤ ±0.5 µm repeatability per adjustment under standard lab conditions (23 °C ± 1 °C, 40–60% RH).
• No lubrication required in vacuum-rated configurations; dry-running bearing interfaces compatible with bake-out up to 120 °C.
• Integrated kinematic mounting interface (M6 threaded holes on base and top plates) for stable stacking and multi-axis integration (e.g., XYZ, tip-tilt-Z, or XYZ-rotation configurations).
• Zero-backlash, non-self-locking drive mechanism enables bidirectional fine-tuning without positional drift after release.

Sample Compatibility & Compliance

The NFP-3561/L series is routinely deployed in alignment-critical photonics workflows involving single-mode fiber pigtails, planar lightwave circuit (PLC) chips, semiconductor laser diodes, DPSS laser cavity components, and integrated photonic test fixtures. Its vacuum compatibility (per ASTM E595-22 outgassing data on request) and particle-shedding performance (< 10 particles ≥ 0.5 µm per cm²/hour, per ISO 14644-1 Class 4 verification protocol) make it suitable for use inside UHV deposition chambers and lithography tool load locks. All units are manufactured under ISO 9001:2015 quality management systems, with traceable calibration records available upon request. While not inherently FDA- or GLP-regulated, the design supports 21 CFR Part 11-compliant documentation when integrated into validated optical assembly lines.

Software & Data Management

As a fully manual stage, the NFP-3561/L requires no firmware, drivers, or software dependencies. Positional data is recorded externally via calibrated micrometer scale reading or integrated with third-party metrology systems (e.g., interferometric encoders, vision-based alignment tools, or laser Doppler vibrometers). Optional engraved reference marks (±0.01 mm tolerance) and orthogonal fiducial grooves support alignment traceability. For automated workflow integration, users may mount the stage onto motorized carriers (e.g., ZOLIX MS series) while retaining mechanical interchangeability and dimensional footprint consistency.

Applications

• Fiber-to-chip coupling alignment in silicon photonics packaging lines.
• Cavity length tuning and mode-matching optimization in DPSS and Ti:sapphire laser resonators.
• Active/passive alignment of micro-optical elements (lenses, isolators, circulators) on wafer-level test benches.
• Sub-micron positioning of AFM/STM probe tips and nanomanipulators in ultra-stable vibration-isolated enclosures.
• Reference-stage calibration for interferometric displacement sensors and autocollimators.
• Thermal expansion coefficient measurement setups requiring long-term positional drift < 50 nm/24 h at ambient stability.

FAQ

Is the NFP-3561/L compatible with ultra-high vacuum environments?

Yes—standard configuration uses vacuum-compatible stainless steel (AISI 304/316), dry-running crossed roller bearings, and matte electropolished surfaces meeting ASTM E595 total mass loss (TML) < 1.0% and collected volatile condensable materials (CVCM) < 0.10%. Optional helium-leak-tested variants available.
What is the maximum load capacity at full extension?

2.5 kg axial load (static) with ≤ 1.5 µm deflection over 25 mm travel; lateral load capacity: 1.2 kg with angular deviation maintained within specification limits.
Can multiple NFP-3561 stages be stacked for 6-axis adjustment?

Yes—the standardized M6 kinematic mounting pattern and orthogonal base/top interfaces enable rigid, co-axial stacking for XYZ + tip/tilt/rotation configurations without cumulative error amplification.
Does ZOLIX provide calibration certificates for individual units?

Traceable calibration reports (per ISO/IEC 17025 principles) are available as an optional service, including micrometer scale linearity verification and straightness mapping using laser interferometry.
Are replacement micrometer knobs or bearing sets available separately?

Yes—ZOLIX maintains full spare parts inventory, including certified replacement micrometers (0–25 mm range, 1 µm graduation), preload-adjustable bearing cartridges, and stainless steel cover plates.
