VANTAGE PRO
6490UV Sensor
The UV Sensor measures the sunburning portion of the UV spectrum.
Its spectral response matches very
closely the Erythema Action Spectrum (EAS), defined by McKinlay and Diffey (1987) and adopted by the
Commission Internationale de l’Eclairage (C.
I.
E.
) as the standard representation of the human skin’s sensitivity to UV radiation.
The sensor measures global solar UV irradiance, the sum of the components of solar
UV transmitted directly and those scattered in the atmosphere.
Scattered UV is a major portion of
global irradiance.
The transducer is a semiconductor photodiode that responds only to radiation in the region of interest.
The diffuser provides an excellent cosine response.
With multiple hard-oxide coatings, the interference filter provides the
Erythema Action spectral response.
It is stable in the presence of heat and humidit
