Spectro-UV uVision 365 Series Handheld Fanless UV-A Lamp

Overview

The Spectro-UV uVision 365 Series is a precision-engineered handheld UV-A lamp designed for mission-critical non-destructive testing (NDT), aerospace component inspection, industrial quality assurance, and forensic evidence visualization. Operating at a tightly controlled peak wavelength of 365 nm ± 5 nm with a full width at half maximum (FWHM) of ≤15 nm, the uVision 365 Series delivers spectrally compliant UV-A irradiance per ASTM E3022-18, ISO 3059:2012, and major OEM specifications including Airbus AITM6-1001 and Rolls-Royce RRES 90061. Unlike conventional UV lamps relying on forced-air cooling, this series employs a passive thermal architecture—eliminating fans to reduce mechanical failure risk, acoustic noise, and particulate contamination in cleanroom or sensitive inspection environments. The result is enhanced operational reliability, extended LED lifetime (>10,000 hours), and consistent spectral output across ambient temperatures from –10 °C to +50 °C.

Key Features

• Fanless thermal management system ensures silent, dust-free operation and improves long-term stability of UV-A output
• IP65-rated enclosure provides protection against low-pressure water jets and ingress of dust—validated for field use in hangars, manufacturing floors, and outdoor NDT sites
• Optimized optical design delivers uniform irradiance across beam diameters ranging from 15 cm to 21 cm at 38 cm working distance, meeting ASTM E3022’s ≥12.7 cm minimum uniform zone requirement
• Integrated white-light LED enables rapid visual context switching without requiring secondary illumination sources—critical for dual-mode inspection workflows
• Multi-platform power architecture supports AC-only operation, NiMH battery (3.5 h runtime), or high-capacity Li-ion battery (up to 10 h), enabling uninterrupted use in remote or mobile applications
• Real-time electronic regulation maintains current ripple <5% under battery operation and <6% under AC, ensuring stable UV-A intensity even during voltage fluctuations
• Automatic thermal shutdown and current derating protocols prevent output drift above 60 °C—fully compliant with ASTM E3022 thermal safety provisions

Sample Compatibility & Compliance

The uVision 365 Series is engineered for compatibility with fluorescent penetrants, magnetic particle suspensions, and forensic dyes conforming to ASTM E1417, E709, and E2912. Its narrow-band 365 nm emission maximizes excitation efficiency while minimizing competing visible background—a key factor in detecting low-fluorescence indications on complex geometries or high-reflectivity surfaces. All units undergo individual photometric validation per ASTM E3022 Annex A1, including spectral radiance profiling, irradiance mapping, and visible light leakage measurement. Full traceable test reports—including calibrated UV-A intensity (µW/cm²), beam uniformity contour, and lux-level visible emission—are supplied with each instrument. Regulatory alignment extends to FAA Advisory Circular AC 43.13-1B (Appendix D), EN 1369, and ISO/IEC 17025-accredited calibration pathways.

Software & Data Management

While the uVision 365 Series operates as a standalone optical instrument, its design supports integration into auditable inspection workflows. Each unit carries a unique serial number registered in Spectro-UV’s device lifecycle database, enabling traceability for GLP/GMP-regulated environments. Optional accessories include NIST-traceable UV-A reference sensors (model UV-SR1) and USB-enabled irradiance loggers compatible with Spectro-UV’s SpectraTrack™ desktop application. SpectraTrack supports time-stamped irradiance logging, export to CSV/PDF, and generation of compliance-ready reports aligned with FDA 21 CFR Part 11 audit trail requirements. Firmware updates—distributed via secure HTTPS portal—maintain ongoing conformance with evolving industry standards including upcoming revisions of ASTM E3022 and ISO 3059.

Applications

• Aerospace: Inspection of turbine blades, composite layups, and fastener holes per Boeing D6-17487 and Airbus AITM6-1001
• Automotive: Detection of micro-cracks in cast aluminum components and weld seams under fluorescent penetrant testing (FPT)
• Power Generation: In-service examination of nuclear-grade piping welds and steam turbine casings
• Forensics: Visualization of latent fingerprints, bodily fluids, and counterfeit document features using standard forensic dyes (e.g., Rhodamine 6G, Basic Yellow 40)
• Electronics Manufacturing: Solder mask integrity verification and conformal coating defect detection
• Research Laboratories: Controlled UV-A exposure studies in materials science, polymer degradation, and photobiology protocols

FAQ

Does the uVision 365 Series meet ASTM E3022-18 spectral and irradiance requirements?
Yes. Every unit is factory-tested to satisfy all mandatory criteria in ASTM E3022-18, including peak wavelength tolerance (365 ± 5 nm), FWHM (≤15 nm), minimum irradiance (≥2,000 µW/cm² at 38 cm), beam uniformity, and visible light emission limits (≤20 lux).

What is the expected service life of the UV-A LEDs?
Rated for >10,000 hours of operation at nominal drive current, with output degradation <10% over lifetime when operated within specified thermal and electrical conditions.

Can the lamp be used in explosive atmospheres?
No. The uVision 365 Series is not intrinsically safe or ATEX-certified. It is intended for general industrial and laboratory use only.

Is calibration certification included with purchase?
Each lamp ships with an individual Certificate of Conformance and a full photometric test report, including spectral scan data, irradiance map, and visible light measurement—all traceable to NIST standards.

How is battery runtime verified?
Runtime is measured under standardized load conditions per IEC 61960, using a constant-current discharge profile at 25 °C ambient. Actual field runtime may vary based on ambient temperature and duty cycle.
