Overview
The NFPR Series Ultra-High-Precision Manual Rotary Stage is a precision mechanical positioning platform engineered for demanding optical alignment, interferometry, and metrology applications where sub-arcsecond angular repeatability and minimal axial runout are critical. Designed and manufactured in-house by ZOLIX (Beijing Zolix Instruments Co., Ltd.), the stage operates on pure mechanical principles—no motors, encoders, or electronics—ensuring intrinsic stability, zero electromagnetic interference, and long-term drift-free performance. Its core kinematic architecture employs a high-stiffness, low-hysteresis cross-roller bearing raceway, enabling smooth, backlash-free rotation with exceptional load-bearing capacity and geometric fidelity. The stage is optimized for integration into vacuum-compatible optical tables, laser cavities, and cryogenic setups where thermal stability and material compatibility are paramount.
Key Features
- Cross-roller bearing assembly sourced from internationally certified suppliers, delivering <1 arcsecond angular repeatability and <2 µm radial runout (TIR) over full 360° rotation
- Monolithic structural body machined from AISI 304 stainless steel—providing dimensional stability across temperature fluctuations (CTE ≈ 17.3 µm/m·K), corrosion resistance, and non-magnetic properties suitable for MRI-adjacent or ultra-high-vacuum environments
- Dual-stage actuation system: coarse adjustment via knurled brass knob (1° per full turn) combined with fine adjustment via calibrated micrometer drum (0.005° resolution, 100 divisions per revolution)
- Integrated locking mechanism with dual-point clamping to suppress torsional creep during static holding; verified under 5 N·m torque load without measurable angular shift
- Standard M6 threaded mounting holes on base plate and top surface, aligned to ISO 8015 GD&T tolerances for repeatable multi-axis stacking
Sample Compatibility & Compliance
The NFPR stage accommodates optical components up to Ø100 mm diameter and 2.5 kg mass without compromising angular fidelity. Its clean-surface finish (Ra ≤ 0.8 µm) and absence of lubricants or outgassing polymers make it compatible with Class 100 cleanroom protocols and UHV systems (base pressure <1×10⁻⁷ Pa). While not certified to ISO 9001 at the component level, ZOLIX maintains ISO 9001:2015 certification for its manufacturing quality management system—including incoming material inspection (per ASTM E112 for grain size verification), in-process metrology (CMM traceable to NIM standards), and final functional testing against internal specification Q/ZLX-NFPR-2023. The design conforms to mechanical safety guidelines outlined in ISO 12100 and incorporates no RoHS-restricted substances per EU Directive 2011/65/EU.
Software & Data Management
As a fully manual, non-electronic device, the NFPR Series requires no firmware, drivers, or software interface. All positional data is recorded manually using the integrated scale drum and verified via external metrological tools such as autocollimators (e.g., Thorlabs AC1300), digital theodolites, or laser tracker systems (e.g., Leica AT960). For GLP/GMP-compliant laboratories, users may document angular settings in electronic lab notebooks (ELNs) with audit-trail-enabled timestamps, satisfying 21 CFR Part 11 requirements when paired with validated ELN platforms. Calibration certificates—traceable to China National Institute of Metrology (NIM)—are provided upon request and include uncertainty budgets per GUM (JCGM 100:2008).
Applications
- Precision alignment of laser cavity mirrors, waveplates, and polarizers in quantum optics experiments
- Angle-resolved reflectance and ellipsometry sample positioning in thin-film characterization
- Reference axis establishment in coordinate measuring machine (CMM) calibration artifacts
- Rotationally symmetric component testing (e.g., lens centration, prism apex angle verification)
- Stable platform for fiber optic collimator coupling and free-space optical interconnects
FAQ
Is the NFPR stage vacuum-compatible?
Yes—its all-metal construction, dry-running cross-roller bearings, and absence of adhesives or elastomers enable operation in high and ultra-high vacuum environments.
What is the maximum allowable axial load?
The stage supports up to 2.5 kg static axial load while maintaining specified runout and angular repeatability; dynamic loads must remain below 1.2 kg to preserve bearing life.
Can I mount this stage on an optical table with M4 holes?
Yes—adapter plates with M4-to-M6 conversion are available upon request; standard mounting uses M6 screws with 10 N·cm torque specification.
Does ZOLIX provide calibration services for the NFPR series?
Yes—NIM-traceable angular calibration (including radial and axial runout mapping) is offered as an optional post-purchase service with documented measurement uncertainty.
Are replacement micrometer drums available separately?
Yes—all mechanical subassemblies—including the calibrated micrometer drum, locking lever, and bearing cartridges—are stocked as spare parts with lead times under 10 business days.
