The UV Index is defined by ISO 17166 and quantifies the risk of sunburn (Erythema Solare) at a given solar UV exposure spectrum. UV Index measurement can be made using radiometers such as photodiode based integrating sensors. This method requires precision matching of the photodiode’s spectral responsivity with the erythema action curve of the human skin and a cosine field of view.
Our components for measurement of the UV Index are summarized in our UVI Measurements Catalog.
- Photodiodes for measurement of the UV Index, various optics and detector chip areas
- UV sensors (TOCONs) with 0 to 5 V voltage output for measurement of the UV Index, various optics
- UV sensor probes for measurement of the UV Index, cosine field of view
- UV Index reference radiometers
- Measurement uncertainty of these sensors is less 5 %, spectral response curve and the field of view (cosine type) in near perfect accordance with the requirements defined in the ISO 17166 standard
