Abstract

981, 745. Photo-electric detectors. J. KONRAD. Oct. 5, 1962 [Nov. 2, 1961], No. 37753/62. Heading G1A. A photo-electric detector for scanning a moving material or a succession of moving objects in which light incident upon the material or objects is reflected thereby to a photosensitive element, comprises means for producing and directing an incident light beam along a desired path and a photosensitive element disposed in the incident light beam path and shielded from direct illumination by the incident light. In the embodiment shown, light from an incandescent lamp 17 is directed by a lens 38 to a convex lens system formed by outer and inner plano-convex lens 23 separated by a cylindrical centre component 22. The light after passing through the lens system 22/23 is reflected by the scanned material 35 on to a photo-cell 26 fixed in an opaque holder 26a secured in an axial bore 24 in the lens system 22/23, the holder 26a preventing the incident light from the lamp 17 from reaching the photo-cell 26.
