An endoscope, exoscope or microscope, including an optical fiber bundle for transmitting light from the proximal end to the distal end, the optical fiber bundle showing a contiguous bundle at the proximal end and a plurality of partial bundles or else individual fibers at the distal end. Furthermore, it shows a light source for coupling light into the one proximal end of the optical fiber bundle and including a multiplicity of individually actuatable individual-light sources arranged in an array-like manner, and a control unit for actuating the individual-light sources using an assignment function which represents the assignment of a proximal fiber end to a partial bundle. Here, the proximal ends of the fibers which are assigned to one partial bundle are arranged on a surface in such a way that proximal ends of fibers assigned to a different partial bundle are arranged therebetween.
