Beschreibung
Zusammenfassung:	The invention provides a multi-laser projection device and a corresponding production method. The multi-laser projection device includes: a plurality of first assemblies (12a, 12b, 12c), each including a fixed assemblage of a respective laser diode (LD1, LD2, LD3) and an associated first collimator lens (1, 2, 3); a second assembly (7a; 7a'; 7a''; 7a''') that forms a fixed assemblage of a beam combiner (7) and a respective second collimator lens (4, 5, 6) that is fastened on an entry surface (E) of the beam combiner (7) and that appertains to a respective laser diode (LD1, LD2, LD3); and a deflection unit (8). The plurality of first assemblies (12a, 12b, 12c), the second assembly (7a), and the deflection unit (8) are mounted in a common housing (90) so as to be adjusted to one another.
