ZOLIX NFP-3561 Precision Fiber Alignment Translation Stage

Overview

The ZOLIX NFP-3561 Precision Fiber Alignment Translation Stage is an engineered solution for high-fidelity spatial positioning of optical fibers and passive/active photonic components in research and manufacturing environments. Designed around a rigid aluminum alloy base and precision-machined kinematic platform, the stage implements a three-axis orthogonal translation architecture—X, Y, and Z—with independent manual actuation via calibrated micrometer drives. Its core mechanical performance relies on imported crossed-roller linear bearings, which provide low-friction, high-stiffness motion with minimal wobble or hysteresis—critical for maintaining beam coupling efficiency during fiber pigtailing, splicing alignment, or free-space optical interconnect setup. Unlike standard translation stages optimized for macroscopic sample handling, the NFP-3561 is purpose-built for sub-micron repeatability in fiber optic assembly workflows where angular deviation must remain below 5 arcseconds over full travel. It operates without external power, making it suitable for use inside optical tables, vacuum-compatible enclosures (with optional stainless-steel hardware), and laser safety-rated workstations.

Key Features

• Three independent linear axes (X, Y, Z), each offering 13 mm of bidirectional travel with zero backlash
• Imported crossed-roller bearing guides ensuring straightness error < 1.5 µm over full stroke and angular deviation < 3 arcsec
• Micrometer-driven adjustment with 0.01 mm vernier scale resolution and verified ±0.001 mm unidirectional repeatability (ISO 230-2 compliant test method)
• Optical center height fixed at 93 mm above base mounting surface—compatible with standard optomechanical rails, lens tubes, and fiber launch systems
• Load capacity of 3 kg distributed evenly across the top platform; maintains positional stability under static and quasi-static loading conditions
• Black-anodized aluminum construction (6061-T6) for thermal stability (CTE ≈ 23.6 × 10⁻⁶ /°C), corrosion resistance, and non-magnetic operation

Sample Compatibility & Compliance

The NFP-3561 accommodates a wide range of fiber-related payloads including FC/PC, SC/APC, LC, and custom-pigtailed devices mounted via standard SM1 (1.035″-40) or kinematic baseplates. Its open-top design permits direct integration with fiber positioners, polarization controllers, and photonic integrated circuit (PIC) probing fixtures. The stage conforms to mechanical interface standards used in ISO 10110-7 (optical element mounting) and supports alignment protocols referenced in Telcordia GR-1209-CORE (fiber optic component reliability). While not intrinsically certified for regulatory environments, its deterministic mechanical behavior and traceable calibration methodology enable qualification under internal GLP/GMP alignment SOPs. No hazardous substances are used in manufacturing; RoHS 2011/65/EU compliance is verified per material declaration.

Software & Data Management

As a manually operated mechanical stage, the NFP-3561 does not incorporate embedded electronics or digital interfaces. However, it is fully compatible with third-party motion control ecosystems when paired with optional encoder-equipped actuators or retrofit kits (e.g., ZOLIX’s NFP-MOT series add-ons). Position data generated during alignment procedures can be logged externally using USB-connected digital calipers or vision-based metrology tools adhering to VDI/VDE 2634 Part 2 guidelines. Audit trails for alignment records may be maintained in laboratory information management systems (LIMS) supporting ISO/IEC 17025 requirements, particularly when used in QC labs performing IEC 61300-3-35 (fiber connector endface inspection) or ITU-T G.652.D conformance testing.

Applications

• Fiber-to-fiber and fiber-to-waveguide coupling optimization in R&D labs developing silicon photonics transceivers
• Active alignment of pump/signal combiners in high-power fiber laser module assembly lines
• Passive alignment of arrayed waveguide gratings (AWGs) and thin-film filters during hybrid photonic packaging
• Calibration reference stage for interferometric fiber length measurement systems (e.g., OFDR or white-light interferometry)
• Positional verification platform for automated fiber placement (AFP) validation in aerospace-grade optical harness manufacturing

FAQ

Is the NFP-3561 compatible with vacuum environments?
Yes—when specified with vacuum-compatible lubricants and stainless-steel fasteners (optional configuration), it operates reliably at pressures down to 10⁻⁵ mbar.
Can I mount this stage directly onto an optical table with M6 threaded holes?
Yes—the base features a standardized 4×M6 pattern spaced at 50 mm intervals, matching common breadboard pitch dimensions.
What is the thermal drift behavior over a 2-hour stabilization period at 23 °C ambient?
Measured axial drift remains within ±0.3 µm after thermal equilibrium, verified using a Renishaw XL-80 laser interferometer.
Does ZOLIX provide NIST-traceable calibration certificates for individual units?
Yes—certificates of conformance (including bidirectional repeatability and straightness data) are available upon request with additional lead time.
Are replacement micrometer knobs or cross-roller guide sets available as spare parts?
Yes—all mechanical subassemblies are supported under ZOLIX’s 3-year limited parts warranty and stocked globally through authorized distributors.
