Abstract: The invention relates to a random light collector device comprising a reflecting cavity (27) configured to enclose a random light source (33, 41) that randomly transmits photons in essentially the whole solid angle of 4rr steradian, the reflecting cavity (27) having an inner wall being adapted to reflect the photons in such a way that at least a portion of once or multiply reflected photons is directed to an output port of the reflecting cavity (27) and guiding means for directing the reflected photons and photons which are directly emitted to the output port (49) to a photodetector (35, 43). According to the invention, the guiding means is a hollow tube (51) having an inner wall being adapted to reflect the photons, wherein a first end of the hollow tube (51) is connected to or positioned adjacent to the output port (49) of the reflecting cavity (27) and wherein the photodetector (35, 43) is provided within the hollow tube (35) or at a second end thereof in such a way that a sensitive area of the photodetector (35, 43) covers the whole cross-section of the second end.
