摘要
The invention relates to an optical element (13) for an emitting unit (8) of an optical acquisition device (3), wherein the optical element (13) comprises a first side (13a) having a reflective first free-form surface (F1) and a second side (13b), which is opposite to the first side (13a), having a refractive second free-form surface (F2). Furthermore, the optical element (13) is designed to transmit a beam bundle (10) incident on the second side (13b) on the optical element (13) at least in large part through the second free-form surface (F2) up to the first free-form surface (F1), to reflect the beam bundle (10) transmitted through the second free-form surface (F2) up to the first free-form surface (F1) at the first free-form surface (F1), and to emit the beam bundle (10) reflected from the first free-form surface (F1) via the second free-form surface (F2). In this case, the first free-form surface (F1) is designed to increase a divergence of the beam bundle (10) incident on the first free-form surface (F1), and the second free-form surface (F2) is designed, upon emission of the beam bundle (10) reflected from the first free-form surface (F1), to reduce the divergence increased during the reflection.
