APFP-XY Two-Axis Translation Stage by ZOLIX

Overview

The APFP-XY Two-Axis Translation Stage is a precision mechanical positioning device engineered for stable, repeatable lateral alignment of optical components in laboratory and industrial optical setups. Designed around a compact, rigid aluminum alloy body with hardened stainless steel adjustment screws, this stage employs fine-pitch micrometer-driven translation to deliver controlled, backlash-minimized motion along orthogonal X and Y axes. Its operational principle relies on direct mechanical coupling between calibrated knurled knobs and linearly guided platforms—ensuring deterministic displacement without hysteresis or thermal drift under ambient lab conditions. The stage is optimized for integration into modular optical breadboards, cage systems, and custom beam paths where sub-millimeter repositioning accuracy and long-term mechanical stability are required—particularly in applications involving laser collimation, interferometer alignment, fiber coupling, and detector positioning.

Key Features

• Orthogonal X–Y translation with independent, non-interfering adjustment mechanisms—each axis offers 3 mm total travel range with tactile feedback and engraved scale markings for visual reference.
• M20×1 external thread interface on the top mounting surface enables direct attachment to standard lens tubes, filter holders, and objective adapters commonly used in visible and near-infrared optical systems.
• Integrated locking screws per axis allow secure fixation after coarse or fine positioning—preventing unintended drift during vibration-prone operations or transport.
• Low-profile design (height < 25 mm) maintains minimal optical path obstruction while supporting payloads up to 1.2 kg without measurable deflection or wobble.
• Black anodized aluminum housing provides corrosion resistance, ESD-safe handling, and compatibility with cleanroom environments (Class 10,000 compliant surface finish).
• No lubricants or consumables required; all moving parts feature dry-running bronze bushings and PTFE-coated leadscrews for maintenance-free operation over >50,000 adjustment cycles.

Sample Compatibility & Compliance

The APFP-XY stage is compatible with optomechanical components conforming to ISO 10110 surface quality standards and ANSI/OEOSC OP1.002 dimensional tolerances. Its M20×1 thread interface aligns with widely adopted photonic component specifications—including Thorlabs SM20-series lens tubes, Newport LMR series mounts, and Edmund Optics #64-527 adapters. While not certified to ISO 9001 at the unit level, ZOLIX manufactures this stage within an ISO 9001:2015-certified facility, with full traceability of raw materials, machining parameters, and final functional testing. All units undergo 100% post-assembly verification of bidirectional repeatability (±1.5 µm) and orthogonal crosstalk (< 0.8% of full-scale motion), documented in individual test reports available upon request.

Software & Data Management

This manual-adjustment stage does not incorporate motorized actuation or digital control interfaces; therefore, it operates independently of software drivers or firmware updates. However, its deterministic mechanical behavior makes it fully interoperable with third-party motion control ecosystems when integrated with optional stepper motor conversion kits (e.g., ZOLIX APFP-XY-M). In automated setups, positional data can be logged via external encoders or vision-based metrology systems adhering to IEEE 1588-2019 time-synchronization protocols. For GLP/GMP-regulated laboratories, users may assign unique asset IDs and record calibration history using standard LIMS templates—no proprietary database schema is imposed.

Applications

• Precise centering and tilt-compensated alignment of plano-convex lenses in collimated beam paths.
• Iterative optimization of fiber-to-waveguide coupling efficiency in silicon photonics packaging stations.
• Coarse/fine registration of CCD or CMOS sensors relative to microscope objectives in quantitative imaging workflows.
• Adjustment of neutral density filter positions in high-dynamic-range laser diagnostics systems.
• Stabilization of retroreflector arrays in Michelson or Fabry–Pérot interferometers requiring periodic realignment.
• Integration into OEM optical modules where space-constrained, passive XY positioning is preferred over motorized alternatives.

FAQ

Is the APFP-XY stage vacuum-compatible?
No—standard units are not rated for vacuum use due to internal lubrication-free but non-outgassing-qualified materials. A vacuum-grade variant (APFP-XY-V) with vented screws and CF-flange mount options is available under separate part number.
Can I stack multiple APFP-XY stages for Z-axis extension?
Yes—ZOLIX provides dedicated stacking brackets (part no. SB-APFP) that maintain orthogonality and minimize cumulative runout (< 5 µm over 3-stage stack). Thermal expansion mismatch between stacked units remains within ±0.3 µm/°C across 15–30 °C.
What is the maximum torque for the adjustment knobs?
Knobs are rated for ≤ 0.15 N·m input torque; exceeding this may deform the brass nut assembly and compromise repeatability.
Does ZOLIX supply calibration certificates with each unit?
Standard shipment includes a factory verification report listing measured travel linearity and crosstalk values. NIST-traceable calibration certificates (ISO/IEC 17025 accredited) are available as a value-added service.
Are replacement screws or mounting hardware available separately?
Yes—M20×1 adapter rings, locking screw sets (SS-304, 2 mm hex), and anti-rotation pins are stocked under ZOLIX spare parts catalog numbers APFP-ACC-01 through APFP-ACC-04.
