摘要
The plastic injection molding (9) is used in an optical system. It has first and second segments designed as Fresnel lenses (9a, 9b) which form the transmitted beam (3) and/or the received beam (5). The lenses are connected by a continuous bridging section, part of the injection molding. An additional light path provides visible optical signals from a light-emitting diode.
