The part (1) has a core (5) including thickness (A) and inserted between a layer (6) and another layer (7), where each of the layers includes thickness (B). The thickness of the core is greater than the thickness of each of the layers. The former layer is connected to the latter layer by a portion. Each of the layers is delimited by a set of faces (12, 13) in contact against the core and another set of faces (14, 15) i.e. concave faces, where concavity is turned toward the core. One of the layers has a central zone (17) to be crossed by a light beam (2) and terminated by an edge. Independent claims are also included for the following: (1) a method for manufacturing an optical part to be crossed by a beam of light emitted by a lighting and/or signaling device (2) a post for manufacturing an optical part to be crossed by a beam of light emitted by a lighting and/or signaling device. |
