Beschreibung
Zusammenfassung:	A beam coupling device (2) includes a light source (30), optical units (4), and a coupling optical system (20). The light source includes light emitters (31) arranged in a first direction (X) and a second direction (Y), to emit light beams having a light ray direction intersecting the first and second directions from each of the light emitters. The optical units (4) are arranged to guide each light beam for each set (3) of light emitters arranged in the first direction in the light source. The coupling optical system is arranged to couple the light beams guided by each optical unit. Each of the optical units is arranged to direct outward the light ray direction (La) of the light beam emitted by a light emitter that is located outside in the first direction for the set of light emitters, to guide the light beam from the light emitter into the coupling optical system.
