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