ZOLIX NFP-x461 Series Ultra-Precision Manual Translation Stage

Overview

The ZOLIX NFP-x461 Series is an ultra-precision manual translation stage engineered for sub-micron positioning stability in demanding optical alignment applications. Based on the Couette-type mechanical principle of constrained linear motion via preloaded crossed roller bearings, it delivers exceptional repeatability and minimal Abbe error through rigid stainless steel construction and kinematically optimized mounting geometry. Designed explicitly for environments where thermal drift, particulate sensitivity, and mechanical hysteresis must be minimized—such as fiber-optic coupling, integrated photonic device packaging, DPSS laser cavity alignment, and vacuum-compatible optical benches—the NFP-x461 achieves a guaranteed sensitivity of 1 µm per graduation and straightness better than ±3 µm over its full 13 mm travel range. Its matte-finished, passivated 304 stainless steel body meets ISO Class 5 cleanroom compatibility requirements and supports bake-out conditions up to 80 °C without dimensional compromise.

Key Features

• Monolithic stainless steel stage body with electropolished matte surface finish—resistant to corrosion, outgassing, and particulate generation; certified for UHV and Class 5 cleanroom use.
• Imported high-precision crossed roller linear guide system with dual-side preload adjustment—ensures zero backlash, consistent rolling resistance, and long-term geometric stability under static load.
• Micrometer-driven actuation mechanism with engraved 10-µm vernier scale and locking collar—enables deterministic positioning with tactile feedback and repeatable zero-reference establishment.
• Modular drive orientation options: central (NFP-1461C), vertical-mount (NFP-1461CZ), right-side (NFP-1461SR), and left-side (NFP-1461SL)—each maintaining identical metrological performance regardless of orientation.
• Standardized M4 and M6 threaded mounting patterns on base and platform—facilitates direct integration with ZOLIX multi-axis stacks, kinematic mounts, and third-party optical tables compliant with ISO 20957-2 mechanical interface standards.

Sample Compatibility & Compliance

The NFP-x461 Series is compatible with standard Ø12.7 mm, Ø25.4 mm, and SM1-threaded optical components, including lens holders, fiber launchers, and waveguide alignment fixtures. All variants conform to RoHS Directive 2011/65/EU and meet ISO 9001:2015 manufacturing traceability requirements. Surface roughness (Ra) is maintained below 0.4 µm across functional bearing interfaces, satisfying SEMI F20-0202 specifications for semiconductor equipment staging. Vacuum-rated models (NFP-1461CZ) are tested per ASTM E595 for total mass loss (TML) <0.5% and collected volatile condensable materials (CVCM) <0.1%, supporting operation at pressures down to 1×10⁻⁷ mbar.

Software & Data Management

As a purely manual stage, the NFP-x461 requires no firmware, drivers, or software dependencies. However, its standardized mechanical interface and deterministic micrometer scaling enable seamless integration into automated workflows via external encoders (e.g., Renishaw RESOLUTE™) or vision-based metrology systems. Calibration certificates—including individual stage straightness maps, sensitivity verification reports, and load-vs-hysteresis curves—are supplied with each unit and archived under ZOLIX’s ISO/IEC 17025-accredited calibration management system. Traceable documentation complies with GLP audit requirements for regulated R&D laboratories.

Applications

• Fiber-to-chip coupling alignment in silicon photonics packaging lines
• Long-term cavity length stabilization in narrow-linewidth DPSS lasers
• Multi-point interferometric reference mirror positioning in gravitational wave detector testbeds
• Mask alignment during micro-optical element fabrication using UV lithography
• In-situ beam path correction in cryogenic optical systems operating below 77 K

FAQ

Is the NFP-x461 suitable for vacuum environments?

Yes—models designated with “Z” suffix (e.g., NFP-1461CZ) are assembled with vacuum-compatible lubricants and undergo helium leak testing to ≤1×10⁻⁹ mbar·L/s.
Can multiple NFP-x461 stages be stacked for XYZ motion?

Yes—right-angle brackets (ZOLIX P/N: BRK-90-SS) and low-profile baseplates (ZOLIX P/N: BP-100×100-SS) are available to construct rigid 2D or 3D configurations without introducing cumulative angular error.
What is the maximum allowable moment load for horizontal use?

At full 13 mm extension, the stage maintains ≤2 arcsec tip/tilt deviation under 0.5 N·m off-axis torque—verified per ISO 10110-7 angular stability protocol.
Does ZOLIX provide NIST-traceable calibration for sensitivity?

Yes—each unit ships with a factory calibration report referencing NIST SRM 2036 step-height standards, with uncertainty ≤±0.15 µm (k=2).
Are custom platform hole patterns available?

Yes—custom machining (e.g., SM1-threaded holes, kinematic triangle patterns) is supported under ZOLIX’s OEM engineering service program, subject to minimum order quantity and lead time validation.
