  • Optical read head having optical fibers inclined towards optical axis and protruding past imaging optics
    Patent number: 5323000
    Abstract: An optical read head contains imaging optics for focusing incident light and light receiving optics arranged concentrically with respect to the imaging optics for receiving the light focused by the imaging optics and reflected from an object. The imaging optics and the light receiving optics are located on the same optical axis, the light receiving optics surrounding the imaging optics. The light receiving optics are also displaced forward in the direction of the incident light with respect to the imaging optics, an input face of the light receiving optics being inclined towards the optical axis. The optical read head is suitable for, among other things, the colour-selective scanning of material webs and other colour patterns and exhibits a high light receiving capability in addition to a high resolution capability.
