Abstract
An illumination system is provided that includes a laser light source and an optical waveguide connected to and/or associated with the laser light source at a proximal end thereof. The illumination system includes a diffuser element at the distal end of the optical waveguide with a longitudinal axis extending perpendicular to the coupling surface of the optical waveguide into the diffuser element. The diffuser element emits light over its active length laterally of the longitudinal axis and has at a base body with a scattering element. The scattering element is aligned along the longitudinal axis substantially parallel or at an angle thereto. An emission intensity homogenizer along the longitudinal axis is provided. The illumination system exhibits an intensity distribution of lateral emission deviating by at most ±50% from an average lateral emission intensity.
