ABSTRACT:
This system collects light emitted by at least one light source (52) and focuses it onto at least one light detection device (54). Preferably, it comprises a first mirror (58) that collects light emitted by the source and focuses it on a second mirror (60) that focuses it in turn onto the device. The system is provided with a chamber that is opaque to all light, particularly ultraviolet radiation, and in which the light source, the light detection device and the mirrors are placed, and means of creating a vacuum in this chamber and filling it with a gas that is transparent to ultraviolet radiation.
