Abstract

The invention relates to an illumination system comprising first illumination means (111) for producing a first illumination beam (IB) and first means (112) for changing the vergence of the first illumination beam. The first illumination means and the first changing means being located along a first optical axis (AA). The illumination system further comprises first means (12) for converting a movement of the first optical axis into a change of vergence of the first illumination beam.
