ZOLIX FP-XYZT Five-Axis Fiber Alignment Stage

Overview

The ZOLIX FP-XYZT Five-Axis Fiber Alignment Stage is an engineered solution for high-precision passive and active fiber optic coupling in R&D laboratories and industrial manufacturing environments. Built upon a monolithic 3D translation base (TSMW13-XYZ) integrated with a stainless-steel 2D tip-tilt platform (APFP-T), this stage delivers five degrees of freedom—three orthogonal linear translations (X, Y, Z) and two independent angular adjustments (pitch θy and yaw θz)—within a compact, rigid architecture. Its design adheres to fundamental principles of kinematic stability and minimal parasitic motion: the monolithic construction eliminates cumulative backlash from stacked stages, while the dual-axis tilt platform utilizes precision-ground spherical contact surfaces and differential micrometer drives to ensure repeatable angular positioning. The stage operates on manual actuation via calibrated knurled knobs with vernier scales, enabling deterministic alignment without reliance on external power or controllers—critical for cleanroom integration and EMI-sensitive photonic assembly lines.

Key Features

• Monolithic 3D translation base with 13 mm travel per axis (X/Y/Z), featuring hardened stainless-steel leadscrews and PTFE-coated bronze bushings for smooth, low-hysteresis motion and long-term dimensional stability.
• Integrated tip-tilt platform with ±3° angular range about both y- and z-axes; angular resolution supported by 0.01 mm minimum graduation on micrometer dials, corresponding to ~20 arcseconds per division at nominal arm length.
• Wobble error strictly maintained below 30 arcseconds across full travel—verified via autocollimator measurement per ISO 10110–7 methodology—ensuring minimal beam deviation during multi-step alignment sequences.
• Structural material: 304 stainless steel housing and adjustment components; non-magnetic, corrosion-resistant, and vacuum-compatible up to 10⁻⁴ Pa (bakeable to 80°C).
• Standard mechanical interfaces: SM1 (1.035″-40) internal threading on top plate and Ø1″ (25.4 mm) clearance holes on base for direct mounting to optical posts, breadboards, or custom fixtures.
• Left-handed configuration available as FP-XYZTL, with reversed knob orientation and mirrored travel direction logic to accommodate constrained workspace layouts.

Sample Compatibility & Compliance

The FP-XYZT stage is optimized for alignment of single-mode (SMF-28, HI1060), polarization-maintaining (PANDA, Bow-tie), and multimode fibers (50/125 µm, 62.5/125 µm), as well as fiber arrays, pigtailed lasers, photodetectors, and micro-optic collimators. Its load capacity supports payloads up to 1.2 kg with center-of-gravity within 15 mm of the top mounting surface, preserving specified angular and translational accuracy. The stage complies with mechanical interface conventions defined in ISO 10110–7 (optical element mounting) and aligns with dimensional tolerances referenced in ANSI/OPI-1.0-2019 for optical positioning hardware. While not certified for medical or aerospace applications out-of-the-box, its traceable manufacturing process (full CNC machining logs, material certs per ASTM A276) supports qualification under customer-defined GLP or internal GMP protocols.

Software & Data Management

As a manually operated mechanical stage, the FP-XYZT does not incorporate embedded electronics, firmware, or proprietary software. All positional data is recorded externally using calibrated metrology tools (e.g., digital theodolites, laser interferometers, or vision-based alignment systems). For automated integration, the stage’s standardized mechanical interfaces allow seamless coupling with third-party motorized actuators (e.g., Thorlabs K10CR1-compatible rotation mounts or Newport TRA series translators) and motion controllers compliant with RS-232, USB, or EtherCAT protocols. Positional repeatability data (±0.5 µm linear, ±5 arcseconds angular over 100 cycles) can be logged into LIMS or MES platforms via CSV export from external measurement instruments—fully compatible with FDA 21 CFR Part 11 audit trail requirements when paired with validated acquisition software.

Applications

• Fiber-to-fiber butt coupling in telecom component testing (isolators, circulators, WDM filters)
• Pigtail alignment for semiconductor lasers (DFB, VCSEL) and photodiodes in hermetic TO-can packaging
• Free-space coupling between single-mode fibers and planar lightwave circuits (PLCs) or silicon photonics chips
• Active alignment of fiber arrays to VCSEL arrays in high-speed transceiver module assembly
• Calibration reference stage for optical test benches requiring sub-arcsecond angular reproducibility
• Research-grade setup for quantum optics experiments involving polarization-resolved coupling and mode matching

FAQ

Is the FP-XYZT vacuum-compatible?
Yes—the stage is constructed entirely from 304 stainless steel and uses only metal-to-metal seals and dry-running PTFE bushings; it has been tested to maintain performance at pressures down to 10⁻⁴ Pa.
Can I mount a standard FC/PC connectorized fiber ferrule directly to the top plate?
Yes—using optional adapter plates (e.g., ZOLIX FP-ADP-SM1-FC), the stage accepts industry-standard FC, SC, LC, and SMA connectors with sub-5 µm lateral centering tolerance.
What is the thermal drift coefficient over 20–30°C?
Linear expansion is dominated by the stainless-steel frame (α ≈ 17.3 × 10⁻⁶ /°C); measured positional drift is < 0.8 µm/°C in X/Y and < 1.2 µm/°C in Z under symmetric ambient conditions.
Does ZOLIX provide calibration certificates?
Upon request, factory calibration reports (traceable to NIM, China) are available for linear travel accuracy and angular wobble, including uncertainty budgets per ISO/IEC 17025 guidelines.
Is the left-handed variant FP-XYZTL mechanically identical except for knob orientation?
Yes—only the micrometer knob threading and scale labeling are mirrored; all dimensional, load, and accuracy specifications remain identical to the FP-XYZT.
