Multi laser projection device and corresponding manufacturing method

The present invention provides a multi-laser projection device and a corresponding manufacturing method. The multi-laser projection device comprises a plurality of first modules (12, 12b, 12c) which (in each case a solid composite of a respective laser diode (LD1, LD2, LD3) and an associated first collimator lens (1, 2, 3) form a second assembly 7a; 7a '; 7a' ', 7a' '') comprising a solid composite (from a beam combiner 7) and a respective second, (at an entry surface e) of the beam (7) fixed and (to a respective laser diode LD1, LD2, LD3) associated collimator lens (4, 5, 6 forms), and a deflection unit (8). The plurality of first modules (12, 12b, 12c), the second assembly (7a) and the deflection unit (8) are in a common housing (90) mounted aligned with each other.
