Transmitting device for a lidar scanner having a scanning mirror covered by a cover element

摘要

The invention relates to a transmitting device, containing an emitting device (1) and a scanning mirror (2), which can be deflected about the center point (MP) of the scanning mirror and which is arranged within a housing (3) having a transparent cover element (4). The cover element (4) is formed, at least in an outcoupling region (4.2), by a portion of a monocentric hemisphere shell (HK) having a curvature center point (K) and is arranged covering the scanning mirror (2) in such a way that the curvature center point (K) and the center point (MP) of the scanning mirror (2) coincide.
