TRANSMITTER DEVICE WITH A SCANNING MIRROR COVERED BY A COLLIMATING COVERING ELEMENT

摘要

A transmitter device preferably containing at least two laser diodes (1₁, …, 1_n) and a scanning mirror (2) that is deflectable about its center point (MP) and is arranged within a housing (3) with a transparent covering element (4). At least in one output coupling region (4.2), the covering element (4) is formed by a section of a monocentric hemispherical shell (HK) with a center of curvature (K), arranged covering the scanning mirror (2) in such a way that the center of curvature (K) and the center point (MP) of the scanning mirror (2) coincide, and, in an input coupling region (4.1), it is formed by an optical block (5) having a toroidal input face (5.1), at least one toroidal output face (5.2₁) and at least two first mirror faces (5.3₁) arranged therebetween for deflecting and pre-collimating the laser beams (S₁, …, S_n).
