ABSTRACT:
A light diffuser for the radial emission of light, which has been fed into the diffuser in axial direction, comprises an optical waveguide, which itself comprises a core and a cladding. The core of the waveguide is exposed at an active region at the distal end. The exposed active region of the core is optically separated from a substance containing scattering particles. In a preferred embodiment, the core is roughened and is embedded in a first layer of an elastic substance, which has a refractive index similar to the refractive index of the cladding and which does not contain any scattering particles. This first layer is embedded in at least one further, second layer of an elastic substance comprising the scattering particles. This substance is surrounded by the outer tube.
