Abstract
The invention relates to a beam transformation module (10) for transforming at least a portion of a light beam (400) entering the beam transformation module into a light beam (500) having a ring-form cross-sectional intensity distribution. The beam transformation module (10;20) comprises an axicon (100), a beam separation element (310), and a deflection element (200), wherein - the axicon (100) and the deflection element (200) are arranged in the optical path of the input light beam (400), such that at least a portion of the input light beam (400) incident on a first surface (110) of the axicon (100) passes through the axicon (100), emerges from a second surface (120) of the axicon (100), and after being deflected by the deflection element (200) towards the axicon (100), reaches the second surface (120) of the axicon (100), passes through the axicon (100) and emerges from the first surface (110) of the axicon (100), forming thereby a transformed light beam (500) having a ring-form cross-sectional intensity distribution (510), and - the beam separation element (310) is configured to spatially separate the input (400) and the transformed light beam (500).
