A method for illuminating is disclosed, which is characterized by the steps of
injecting (1) the light beam (13) from a laser (9) into a
optical element (19), which spectrally broadens the light of the light beam
(13) and shaping (3) the spectrally broadened light (31) to
form an illumination light beam (29). An instrument (7) for illuminating
is furthermore disclosed, which comprises a laser (9) that emits a light
beam (13), which is directed onto a optical element (19) that spectrally
broadens the light from the laser. A optical means (33) which shapes the
spectrally broadened light (31) to form an illumination light beam (29)
is arranged downstream of the microstructured optical element (19).
