Optical Sensors & Detector – UV Calibration
UV-Arc Validation Set
Precision UV-Arc Validation Set for Accurate Verification and Calibration of UV Radiometers and Sensors
The UV-Arc Validation Set is a high-precision reference system designed to verify and calibrate UV radiometers, photodiodes, and measurement heads under controlled optical conditions. It utilises a stabilised UV arc lamp with known spectral output and an integrated reference detector calibrated to NIST/PTB standards, providing traceable irradiance values across UVA, UVB, and UVC regions. The system enables laboratory-grade validation of sensor linearity, spectral accuracy, and repeatability. Featuring adjustable output intensity, interchangeable optical filters, and a stable power regulation circuit, the UV-Arc Validation Set simulates real-world UV exposure while maintaining measurement consistency. It is ideal for R&D laboratories, calibration centres, and industrial QA departments requiring certified UV verification standards. Compact, robust, and simple to operate, it ensures accurate performance testing for UV detectors, disinfection sensors, and radiometric instruments.
Understanding UV-Arc Validation Set
The UV-Arc Validation Set provides a traceable UV light reference using a precisely regulated arc discharge lamp that emits a continuous spectrum across 200–400 nm. By positioning the test sensor at a defined distance from the source, users can verify irradiance readings against a certified reference detector. The included control unit stabilises lamp intensity and monitors output in real time. Designed for repeatable calibration and instrument verification, it allows comparative testing of multiple UV sensors under identical conditions. The system’s portability and reproducibility make it indispensable for field validation, sensor production testing, and radiometer recalibration.
