PROBLEM TO BE SOLVED: To provide an endoscope light source safety system. SOLUTION: An endoscope light source safety system, includes visible light transmitted along an illumination path, one or more sources for providing radiation along at least a portion of the illumination path, an optical element for emitting the radiation from the one or more sources into the illumination path, an illumination attenuator connectable to the illumination path for receiving the visible light and the radiation, a reflector connected to the illumination attenuator for transmitting the visible light and returning at least a portion of the radiation, and one or more detectors for receiving the returned radiation from the reflector and for generating a signal indicative of the receipt of visible light by the illumination attenuator.
