Abstract
A transmitting device, preferably containing at least two laser diodes and a scanning mirror, which is deflectable about its center (MP) and is arranged in a housing with a transparent cover element. The cover element is formed, at least in a coupling-out region, by a section of a monocentric hemispherical shell (HK) with a center of curvature (K) and is arranged to cover the scanning mirror in such a way that the center of curvature (K) of the hemispherical shell (HK) and the center (MP) of the scanning mirror coincide, and is formed in a coupling-in region by an optical block, comprising a toroidal entrance surface, in the special form of a cylindrical surface, at least one toroidal exit surface and at least two first mirror surfaces arranged between them, for deflecting and pre-collimating the laser beams.
