Title:
OPTICAL MODULE AND METHOD FOR MANUFACTURING OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2023/026772
Kind Code:
A1
Abstract:
This optical module (1A) comprises: a lens unit (5) having a collimating lens array (4) that makes a plurality of beams parallel with one another, the plurality of beams being outputted by a multi-emitter semiconductor laser bar (2) having a plurality of light emission points; and element units (51a, ..., 51n) having light-emitting elements (41a, ..., 41n) arranged further forward than the lens unit (5) in the direction in which the beams are propagated, each of the element units (51a, ..., 51n) furthermore having a retaining member (6a, ..., 6n) for retaining the light-emitting elements (41a, ..., 41n). The direction of warping in the collimating lens array (4) and the direction of warping in the light-emitting elements (41a, ..., 41n) are identical to the direction of warping of a line connecting the plurality of light emission points, and each of the retaining members (6a, ..., 6n) is joined in the propagation direction by a third joining member (11a, ..., 11n).
