Title:
OPTICAL ASSEMBLY AND LASER MODULE HAVING AN OPTICAL ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2014/166616
Kind Code:
A3
Abstract:
The invention relates to an optical assembly, comprising: a light-emitting element (2) which has a plurality of light outlet apertures (4) arranged in a row, each emitting a divergent bundle of rays (5), wherein the central rays (10) of the bundles of rays (5) are located in a common reference plane (11), and have a common first propagation direction; a first heat-conducting body (14) having a base surface (15), and a fastening surface for the light-emitting element, and a stop surface (16); a first optical element (17) that reduces at least the divergence (7) of the bundles of rays with respect to the direction that is vertical to the reference plane (11), wherein the first optical element is mechanically connected to the first heat-conducting body (14); a second optical element (18), which brings about a rotation of the bundles of rays of each of the individual emitters by a right angle about the propagation direction, wherein the rotated bundles of rays leave the second optical element in a second propagation direction (12), wherein after the second optical element, the central rays of the bundles of rays are located in a second plane (13) that is parallel to the reference plane (11); a third optical element (19) arranged in the beam path after the second optical element, which reduces the divergence (8) of the bundles of rays of the emitters rotated by the second optical element in a direction that is vertical to the reference plane. The invention is characterized in that a holder (20) for fastening the third optical element to the first heat-conducting body (14) is provided, which holder (20) has a first mounting surface (21) that is connected in a planar manner to the stop surface (16) of the first heat-conducting body (14), at least partially, and a second mounting surface (22), to which the third optical element (19) is fastened. The second mounting surface is vertical to the reference plane (11) and parallel to the incident direction (12) of the central rays of the bundles of rays falling onto the third optical element.
