Abstract
A device includes an optical path and a beam profile redistributor arranged in the optical path to receive an input light beam. The beam profile redistributor is configured to convert the received input light beam so that at least one output light beam of the device includes, (i) in a near field and/or at the beam profile redistributor, a redistributed beam intensity profile compared to at least one further output light beam when the beam profile redistributor is not present, (ii) within a given measuring aperture at a position along the optical path in the near field, a lower output light power compared to the at least one further output light beam, and (iii) in a far field, at least substantially the same beam intensity profile compared to the at least one further output light beam. Other embodiments are also described.
