ABSTRACT:
A light-conducting fiber, or a bundle of such fibers, is provided with a ht-absorbing shield extending beyond an end face of the fiber or bundle proximal to a light-reflecting object. The shield forms a light-guiding channel, of a length substantially exceeding its width, which limits the effective aperture angle of the fiber or bundle to considerably less than its inherent value on the order of 60.degree..
