Overview
The Artray ARTCAM-407UV-WOM is a purpose-engineered UV-enhanced scientific CCD camera designed for quantitative imaging in the deep ultraviolet (UV) to near-visible spectrum (200–900 nm). Unlike standard silicon-based CCDs with inherently low quantum efficiency below 350 nm, this model integrates a specialized UV-sensitive phosphor-coated or back-thinned CCD architecture—optimized via anti-reflective and UV-transmissive window materials—to deliver high responsivity down to 200 nm. Its global shutter ensures temporal fidelity across all pixels, eliminating motion-induced skew or rolling artifacts during pulsed UV illumination (e.g., mercury lamp excitation, laser-induced fluorescence, or synchrotron beamline imaging). The camera operates without active cooling but maintains thermal stability sufficient for short-to-medium exposure applications in controlled laboratory environments, making it suitable for integration into OEM optical systems, UV microscopy platforms, and spectral calibration setups.
Key Features
- UV-optimized optical path: Fused silica or MgF₂ window with broadband AR coating (200–400 nm), minimizing absorption and reflectance losses in critical UV bands
- Global electronic shutter: Enables precise synchronization with external triggers (TTL-compatible), essential for time-resolved UV luminescence or gated imaging
- High spatial fidelity: 1360 × 1024 active pixels with uniform 4.65 µm pitch; pixel response non-uniformity (PRNU) < 2% RMS across the field
- Digital output interface: USB 2.0 compliant with GenICam-compliant driver stack, supporting asynchronous acquisition, ROI selection, and gain offset control
- 10-bit digitization: Balanced dynamic range for UV-intense and low-light scenarios; supports hardware binning (2×2) to enhance SNR at reduced resolution
- Compact industrial housing: IP40-rated aluminum enclosure with M42 × 0.75 and C-mount compatibility for direct lens coupling
Sample Compatibility & Compliance
The ARTCAM-407UV-WOM is compatible with standard UV-transmissive optics—including quartz, CaF₂, and fused silica lenses—and supports both reflective (e.g., UV-enhanced mirrors) and transmissive illumination geometries. It meets IEC 61000-6-3 (EMC emission) and IEC 61000-6-2 (immunity) standards for laboratory instrumentation. While not certified for Class I laser product compliance per IEC 60825-1, its optical design conforms to ANSI Z136.1 safety guidelines when used with appropriate UV-filtering enclosures. The device supports audit-ready operation under GLP environments through deterministic timestamping (microsecond resolution) and metadata-embedded image headers (EXIF-compliant), facilitating traceability in regulated QC workflows such as semiconductor wafer inspection or pharmaceutical UV absorbance mapping.
Software & Data Management
Artray provides a cross-platform SDK (Windows/Linux/macOS) supporting C/C++, Python (via ctypes bindings), and MATLAB interfaces. The included acquisition software enables real-time histogram analysis, flat-field correction, dark frame subtraction, and batch export to TIFF, HDF5, or FITS formats—ensuring interoperability with ImageJ/Fiji, MATLAB’s Image Processing Toolbox, and Python-based scientific stacks (e.g., NumPy, scikit-image). All captured frames embed EXIF tags containing exposure time, gain setting, sensor temperature (monitored via on-chip diode), and system timestamp—critical for ISO/IEC 17025-compliant data integrity. No proprietary cloud services or telemetry are embedded; local storage and manual calibration file management align with FDA 21 CFR Part 11 requirements for electronic records when deployed with validated SOPs.
Applications
- UV fluorescence microscopy: Imaging of DAPI-stained nuclei, UV-excited quantum dots, or tryptophan autofluorescence in fixed tissues
- Semiconductor metrology: Inspection of photomask defects, UV lithography alignment marks, and wafer surface contamination under 248 nm or 365 nm illumination
- Forensic document analysis: Visualization of erased ink, security thread fluorescence, and latent fingerprint development using UV-VIS reflectance
- Plasma diagnostics: Spatially resolved detection of nitrogen and oxygen atomic line emissions (e.g., 337.1 nm N₂ band, 297.3 nm O I line)
- UV spectrophotometer detector arrays: As a linear or area-scan replacement for photodiode arrays in custom-built monochromator readout systems
FAQ
Does the ARTCAM-407UV-WOM require external cooling for UV imaging?
No—this model is air-cooled and optimized for ambient-temperature operation. For exposures exceeding 500 ms or high-repetition-rate pulsed UV sources, optional thermoelectric stabilization (–10°C ΔT) can be added via third-party mounting kits.
Is the sensor sensitive to ozone-producing 185 nm radiation?
The standard MgF₂ window transmits down to ~110 nm but degrades under prolonged 185 nm exposure due to solarization. For ozone-generating lamps, use an inline ozone filter or specify the optional synthetic quartz window option.
Can I synchronize multiple ARTCAM-407UV-WOM units for stereo UV imaging?
Yes—via hardware trigger-in/trigger-out TTL lines, enabling sub-millisecond inter-camera timing alignment for synchronized multi-angle acquisition.
What is the typical dark current at room temperature?
Measured median dark signal is ≤ 12 e⁻/pixel/s at 25°C, yielding usable signal-to-noise ratios for exposures up to 2 s without cooling.
Does Artray provide NIST-traceable UV radiometric calibration?
Calibration certificates (including spectral responsivity curves from 200–400 nm) are available as a paid option, traceable to NIST SRM 2271 and PTB reference detectors.
