Abstract
A description is given of a sensor for measuring the UV fraction of a radiation, comprising a photochromic transducer consisting of a photochromic material (3) with characteristics of reversible photochromism, whose absorbance varies as a function of the UV fraction of the radiation (R) incident on the photochromic material. An optical path (7) is provided to guide a light signal through said photochromic material and collect a return light signal, whose value is proportional to the level of absorbance of the photochromic material.
