Cinogy AUT-NFBP Series Fully Automated Near-Field Beam Profiler

Overview

The Cinogy AUT-NFBP Series Fully Automated Near-Field Beam Profiler is an engineered solution for high-fidelity spatial characterization of laser beams in the near-field regime. Based on the proven CinCam imaging sensor platform and integrated with the RayCi software suite, this system implements a precision motorized translation stage to enable automated, repeatable beam-waist scanning across axial (z) and transverse (x/y) dimensions. Unlike conventional near-field profilers constrained by focal length limitations and thermal loading risks at high irradiance, the AUT-NFBP architecture decouples optical magnification from mechanical positioning—allowing accurate profiling of tightly focused, high-power beams (up to 500 W CW) regardless of focal length or working distance. Its core measurement principle relies on pixel-resolved intensity mapping via calibrated CMOS/InGaAs sensors, supported by ISO 11146-compliant beam width (D4σ, knife-edge, FWHM), centroid position, ellipticity, and M² estimation algorithms where applicable.

Key Features

• Automated z-scan capability with programmable step resolution down to 1 µm, enabling precise determination of beam waist location and depth of focus
• Wide spectral response spanning 200–1600 nm—covering deep UV excimer sources, visible diodes, NIR fiber lasers, and SWIR InGaAs-emitting systems
• Modular optical train with interchangeable magnification objectives (4× to 100×), optimized for sub-micron spot resolution (≥1 µm minimum measurable diameter)
• Thermally robust mechanical design supporting both air-cooled and water-cooled configurations for stable operation under sustained high-power exposure
• Multi-interface detector compatibility (USB 2.0, USB 3.0, GigE Vision) ensuring seamless integration into industrial automation environments and laboratory DAQ systems
• Fully compliant with ISO 13694 (laser beam profile measurement) and aligned with ASTM E1423 (beam parameter definitions) for traceable metrology

Sample Compatibility & Compliance

The AUT-NFBP accommodates continuous-wave (CW) and quasi-CW laser sources across industrial, scientific, and medical domains—including fiber-coupled diode lasers, ultrafast amplifiers (with optional pulse picker synchronization), CO₂ lasers (via reflective optics configuration), and UV excimer systems. Its non-contact, camera-based detection avoids perturbation of beam propagation and eliminates alignment-induced errors common in scanning-slit or knife-edge methods. All hardware and firmware comply with CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). The RayCi software supports audit-trail logging and user-access controls consistent with GLP/GMP documentation practices per FDA 21 CFR Part 11 when configured with appropriate IT infrastructure.

Software & Data Management

RayCi provides a unified interface for acquisition, real-time visualization, batch analysis, and report generation. It includes built-in calibration routines for pixel pitch, quantum efficiency, and non-uniformity correction (NUC), as well as dynamic range optimization for high-contrast beam profiles. Export formats include CSV, HDF5, TIFF, and MATLAB-compatible .mat files—enabling post-processing in third-party tools such as Python (SciPy, OpenCV), MATLAB, or LabVIEW. Version-controlled software updates are delivered via secure HTTPS channels, with release notes documenting changes relevant to ISO/IEC 17025-compliant calibration workflows. Remote operation is supported via TCP/IP API for integration into automated test benches or production line monitoring systems.

Applications

• Characterization of ultrafast laser focusing optics in micromachining and ablation process development
• Validation of fiber-to-free-space coupling efficiency and mode field diameter matching in telecom component manufacturing
• Qualification of high-brightness diode stacks used in direct-diode material processing systems
• Beam diagnostics for EUV lithography light sources and synchrotron beamlines requiring sub-µm spatial resolution
• Research-grade M² and BPP (beam parameter product) evaluation under variable thermal lensing conditions
• Verification of beam homogeneity and hot-spot formation in medical laser delivery systems (e.g., dermatology, ophthalmology)

FAQ

What is the minimum measurable beam diameter supported by the AUT-NFBP system?
The system resolves features down to 1 µm using high-magnification objectives and pixel-binning–optimized acquisition modes.
Can the AUT-NFBP measure pulsed lasers?
Yes—when synchronized with external trigger signals, it captures single-shot or averaged profiles of nanosecond- to femtosecond-duration pulses.
Is RayCi software validated for regulated environments?
RayCi supports 21 CFR Part 11 compliance when deployed with network authentication, electronic signatures, and immutable audit logs.
How is calibration traceability maintained?
Cinogy provides NIST-traceable calibration certificates for spatial scale and responsivity, updated annually or per ISO/IEC 17025 internal procedures.
Does the system support custom objective lenses?
Yes—the modular mount accepts standard C-mount or F-mount optics; custom telecentric or UV-optimized lenses can be integrated upon request.
