ABSTRACT:
An ultraviolet radiation detector10, detecting an ultraviolet radiation transmitted through or reflected from a measurement sample15from a light beam including at least the ultraviolet radiation, is characterized by spectral means19for spectrally splitting the ultraviolet radiation from the light beam and photodetection means20for detecting the ultraviolet radiation spectrally split by the spectral means19, the photodetection means20including a photoelectric surface detecting only the ultraviolet radiation and formed of an element selected from In, Ga, N, Al, O and Cs.
