The UV-REF-LED functions as a portable, spectrally defined reference source for comparing or calibrating UV detectors. Its built-in driver electronics deliver constant current to the LED, ensuring stable output over time and temperature. Available in models covering 254 nm (UVC), 310 nm (UVB), and 365 nm (UVA), it allows precise wavelength-specific calibration. When used with photodiodes or radiometers, the UV-REF-LED provides a known irradiance level for verifying responsivity or instrument drift. Compact and energy-efficient, it is indispensable in calibration laboratories, UV system maintenance, and R&D applications requiring traceable UV output verification.

Traceable UV Reference Output

Each UV-REF-LED unit is calibrated to NIST/PTB standards, providing a reliable irradiance reference for laboratory and field calibration of UV detectors.

Spectrally Stable Illumination

Temperature-stabilised electronics and constant-current drive maintain spectral stability within ±1 nm and power variation below 1 %, even during long test runs.

Multiple Wavelength Options

Available in UVC (254 nm) for sterilisation sensor calibration, UVB (310 nm) for photobiological testing, and UVA (365 nm) for industrial and curing sensor validation.

Compact and Portable Design

Lightweight and self-contained, the UV-REF-LED enables on-site sensor verification without requiring complex optical alignment or power conditioning.

Plug-and-Play Operation

Powered via standard USB or DC input, it can be directly interfaced with calibration benches, data loggers, or handheld radiometers.

Long-Term Stability

The LED module’s lifetime exceeds 10 000 hours, ensuring minimal recalibration frequency and dependable reference output over years of use.

Comprehensive Compatibility

Supports UV sensors, photodiodes, and radiometers from various manufacturers, simplifying cross-instrument verification and calibration processes.

By delivering stable, reproducible, and traceable UV output, the UV-REF-LED serves as the foundation for accurate detector calibration and performance assurance in industrial, medical, and research photonics applications.
