DataRay WinCamD-IR-BB Mid-Infrared Beam Profiler

Overview

The DataRay WinCamD-IR-BB is a high-resolution, uncooled mid-infrared (MIR) beam profiling camera engineered for quantitative spatial characterization of laser beams operating across the 2–16 µm spectral band. Unlike cooled photon-based detectors, it employs a thermally stable vanadium oxide (VOx) microbolometer focal plane array—enabling direct, real-time measurement of both continuous-wave (CW) and pulsed MIR sources—including CO₂ lasers (10.6 µm), quantum cascade lasers (QCLs), optical parametric oscillators (OPOs), and broadband thermal emitters—without cryogenic cooling or mechanical choppers. Its 640 × 480 pixel architecture delivers sub-17 µm spatial sampling over a 10.88 × 8.16 mm active area, supporting ISO 11146-compliant beam width (D4σ, knife-edge, FWHM), ellipticity, centroid position, and M² estimation when integrated with appropriate collimation and relay optics. Designed for laboratory, manufacturing, and field-deployable use, the WinCamD-IR-BB provides traceable, reproducible beam diagnostics essential for laser system commissioning, alignment validation, and long-term stability monitoring in regulated environments.

Key Features

• Uncooled VOx microbolometer sensor with native 2–16 µm spectral response—eliminates need for liquid nitrogen or thermoelectric coolers
• 14 ms thermal time constant enables accurate capture of pulses at repetition rates ≥1 kHz and stable CW beam profiling
• USB 3.0 interface supplies full power and data bandwidth—no external power supply or frame grabber required
• 14-bit analog-to-digital conversion ensures >16,000 intensity levels for high dynamic range analysis of asymmetric or clipped beams
• Real-time frame rate of 7.5 fps at full resolution supports live alignment feedback and drift tracking over extended durations
• Integrated lens mount accepts standard C-mount optics; optional polarization-maintaining beam samplers and IR-transmissive lens kits available for customized optical paths

Sample Compatibility & Compliance

The WinCamD-IR-BB is compatible with free-space MIR beams up to Ø10 mm (with optional relay lenses) and supports non-contact, non-perturbative measurement of low-to-medium power density beams (typical max fluence < 100 mJ/cm² for nanosecond pulses; < 1 W/cm² for CW). It complies with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity), carries CE marking per EU Machinery and EMC Directives, and conforms to RoHS 2011/65/EU material restrictions. While not certified for medical device use under FDA 21 CFR Part 820, its measurement traceability aligns with ISO/IEC 17025 calibration practices when used with NIST-traceable reference sources. Data integrity workflows—including timestamped image logging, metadata embedding (exposure, gain, ROI), and audit-ready export formats (TIFF, CSV, HDF5)—support GLP and GMP-aligned documentation requirements.

Software & Data Management

DataRay’s proprietary WinCamD software (v6.x, Windows 10/11) provides full control, visualization, and analysis capabilities. It implements ISO 11146-1/2 beam parameter algorithms—including second-moment (D4σ), knife-edge integration, and beam propagation modeling—and exports results to Excel-compatible CSV or MATLAB-readable MAT files. The software supports multi-camera synchronization, time-series beam centroid tracking (sub-pixel accuracy), and automated pass/fail reporting against user-defined tolerances. All raw frames are stored with embedded EXIF-like metadata (timestamp, exposure time, gain setting, lens ID), enabling retrospective analysis and compliance with 21 CFR Part 11 principles when paired with validated IT infrastructure and electronic signature protocols.

Applications

• CO₂ laser system commissioning and maintenance—profile stability, mode structure, and hot-spot detection during cavity alignment
• Quantum cascade laser (QCL) characterization in spectroscopy and gas sensing platforms
• Optical train verification in FTIR and hyperspectral imaging systems
• Beam drift quantification during thermal cycling of industrial laser delivery optics
• Non-destructive evaluation of IR-transparent materials (e.g., ZnSe, Ge, CaF₂) using structured illumination
• Validation of beam homogenizers, diffractive optical elements (DOEs), and fiber-coupled MIR sources
• Academic and defense research involving tunable FIR sources and terahertz precursor systems

FAQ

Does the WinCamD-IR-BB require external cooling or a chopper wheel?

No—its uncooled VOx microbolometer operates stably at ambient temperature without thermoelectric coolers or mechanical modulation.
Can it measure pulsed CO₂ lasers with 100 ns pulse widths?

Yes, provided average power remains within detector damage thresholds; the 14 ms time constant supports PRFs ≥1 kHz but does not resolve individual sub-millisecond pulses.
Is calibration traceable to NIST standards?

DataRay provides factory calibration reports with uncertainty budgets; end-user recalibration using blackbody or stabilized MIR sources is recommended annually per ISO/IEC 17025 guidelines.
What optical interfaces are supported for integration into existing setups?

Standard C-mount lens adapter; optional kinematic mounts, pellicle beam samplers, and AR-coated ZnSe focusing lenses facilitate OEM and custom optical path integration.
How is data security and audit readiness ensured?

WinCamD software logs all acquisition parameters and timestamps; exported datasets include SHA-256 checksums and support digital signing when deployed within validated network environments compliant with 21 CFR Part 11 Annex 11.
