Photometric and radiometric calibration services

A pioneering accredited photo-radiometry laboratory in Italy, with recognised expertise in selected photometric and radiometric quantities.

From visible light and ultraviolet radiation to spectral and solar irradiance, our Padua laboratory provides calibration services for a wide range of optical measuring instruments and sources.

Calibration is performed by comparison with traceable reference standards using dedicated optical benches, reference lamps, radiometers and integrating-sphere systems. Services are available with ISO/IEC 17025 accredited calibration certificates or ISO 9001 calibration reports, depending on the instrument and measurement quantity.
