Abstract
An elongated optical element is proposed with a core (2, 11), with several optical transmission units extending in the longitudinal direction of the element and affixed to the surface of the core (2, 11) with a layer (3,13) of a hot-melt adhesive, the layer (3,13) extending through cavities (7) disposed between the surface (6,14) of the core (2,11) and the transmission units, wherein the hot-melt adhesive can swell in water and wherein the layer thickness of the hot-melt adhesive is less than the diameter of the transmission units. Also described is a method for fabricating the element.
