Coupling device for connecting a light source to an optical fiber

摘要

A coupling device for coupling a light source, which emits light in accordance with Lambert's law, to a bundle of optical fibers by way of an optical rod. The largest dimension of the source at most equals half the diameter of the core of the coupling rod. The source and the coupling rod are secured in a flexible, elastic support which maintains a distance between a light-emissive surface of the source and the oppositely situated end of the coupling rod. This distance at most equals one third of the diameter of the core of the coupling rod.
