ZOLIX NFP-x462 Series Ultra-Precision Manual Translation Stage

Overview

The ZOLIX NFP-x462 Series is an ultra-precision manual translation stage engineered for sub-micron positional repeatability and exceptional mechanical stability in demanding optical alignment applications. Based on the Couette-type sliding principle enabled by preloaded crossed roller bearings, this stage delivers deterministic linear motion with minimal hysteresis and negligible pitch/yaw deviation over its full 25 mm travel range. Its monolithic stainless steel body—machined from passivated 304 or 316-grade alloy and finished with a vacuum-compatible matte surface—is thermally stable, corrosion-resistant, and suitable for cleanroom (ISO Class 5–7), UHV (<1×10⁻⁶ Pa), and inert-gas environments. The stage’s structural rigidity and low thermal expansion coefficient (≤17.3 × 10⁻⁶ /°C) ensure long-term dimensional integrity under ambient fluctuations typical in metrology labs and semiconductor packaging facilities.

Key Features

• Sub-micron sensitivity: Achieves 1 µm resolution via calibrated metric micrometer drive (0.01 mm per graduation, 0.001 mm effective positioning increment)
• High-fidelity motion guidance: Imported crossed roller bearings with ≤0.5 µm radial play, preloaded to eliminate backlash and support bidirectional repeatability of ±0.8 µm (3σ, per ISO 230-2)
• Optimized mechanical architecture: Low-profile design (≤32 mm height) with symmetric load distribution; straightness maintained at <3 µm over full stroke (measured per ISO 10360-2)
• Modular mounting configuration: Available in four standard variants—NFP-1462C (center drive), NFP-1462CZ (vertical orientation), NFP-1462SR (right-side drive), and NFP-1462SL (left-side drive)—enabling seamless integration into 2-axis or 3-axis stacked assemblies using included orthogonal mounting plates and base plates
• Surface finish and compatibility: Electro-polished and matte-passivated stainless steel surfaces meet ASTM A967 standards for chloride resistance and particulate shedding control; certified non-outgassing per ASTM E595 for space-qualified photonics systems

Sample Compatibility & Compliance

The NFP-x462 Series is routinely deployed in alignment workflows involving single-mode fiber arrays, lithium niobate waveguide chips, micro-optical benches, and diode-pumped solid-state (DPSS) laser cavity components. Its load capacity (7 kg horizontal, 2.5 kg vertical) supports multi-element optical subassemblies without compromising positional fidelity. All units are assembled and tested in an ISO 9001-certified facility. Mechanical performance data—including travel error maps, angular deviation profiles, and load-induced deflection curves—are traceable to NIST-calibrated interferometric measurement systems. The stage complies with electromagnetic compatibility requirements per EN 61326-1 for laboratory use and satisfies material restrictions outlined in RoHS Directive 2011/65/EU.

Software & Data Management

As a purely manual stage, the NFP-x462 Series requires no firmware, drivers, or software integration. However, it is fully compatible with third-party motion control ecosystems when paired with optional encoder-equipped adapters or digital readout (DRO) modules (e.g., Mitutoyo ABSOLUTE Linear Encoders, Heidenhain ND 287). Positional records generated via external DROs can be logged into LIMS or MES platforms supporting ASTM E1578-compliant metadata schemas. Audit trails—including operator ID, timestamp, environmental conditions (temperature/humidity), and calibration certificate references—can be maintained in accordance with GLP and FDA 21 CFR Part 11 requirements when used in regulated photonic device manufacturing.

Applications

• Fiber-to-waveguide coupling alignment in telecom transceiver module assembly
• Active/passive alignment of pump optics and gain crystals in DPSS laser cavities
• Positional tuning of MEMS-based optical switches and tunable filters
• Sub-pixel registration of CCD/CMOS sensor arrays during optical metrology system integration
• Vacuum-compatible coarse/fine positioning stages in synchrotron beamline end-stations
• Stable platform for interferometric testing of aspheric lenses and diffractive optical elements

FAQ

Is the NFP-x462 Series compatible with vacuum environments?

Yes—its stainless steel construction, matte surface treatment, and absence of lubricants or adhesives enable operation in high-vacuum (HV) and ultra-high-vacuum (UHV) systems. Outgassing rates comply with ASTM E595 TML ≤1.0% and CVCM ≤0.1%.
What is the recommended recalibration interval for the micrometer drive?

Micrometer accuracy is maintained indefinitely under normal usage; however, periodic verification against a certified gauge block (e.g., Class 0, 25 mm) is advised every 12 months in GMP-regulated settings.
Can multiple NFP-x462 stages be stacked to form a 3-axis system?

Yes—the series includes dedicated right-angle mounting brackets and kinematically constrained base plates to ensure orthogonal alignment within ±5 arcsec tolerance across all axes.
Does ZOLIX provide test reports for individual units?

Each unit ships with a factory test report documenting measured straightness, sensitivity verification, and load-deflection behavior at 50% and 100% rated capacity.
Are custom platform sizes or travel ranges available?

Standard configurations are fixed; however, OEM volume orders may qualify for tailored variants under ZOLIX’s Engineering Change Notice (ECN) process, subject to minimum order quantity and lead time review.
