A light collector for collecting light reflected from a photoconductive surface bearing a developed image and scanned by a flying spot scanner. The collector includes a rod-like element, the central core of which is made up of a relatively rigid transparent material. The core is encased by a cladding material having an index of refraction lower than that of the core. A light diffusing coating is provided on the outer surface of the cladding material, except for a slit-like aperture for receiving light reflected from the photoconductive surface. In an alternate embodiment, the dimention of the light receiving aperture is varied uniformly along the length of the collector, the size of the aperture at the collector center being at a minimum. In a further embodiment, a slit-like axial section of the cladding material opposite the light receiving aperture is removed and replaced by a highly reflecting, light diffusing coating.
