In a photodetector for ultraviolet light radiation, the UV light to be detected is converted into light radiation of larger wavelengths in a scintillator layer (25) preferably applied to the surface of said filter (22), from which light emerges, after the UV light passes through a quartz lens (1) and a filter (22), which permits the passage of UV light. The silicon photodiode (24) exhibits a greater sensitivity to the light radiation of larger wavelengths. Optionally, an additional cut-off filter (26) can be used in order to improve the sensitivity loss of the system to a level ranging from 350 to 400 nm.
