Abstract

Un élément optique (EO) équipe un bloc optique (BO) sans glace et comprend une source (SP) délivrant des photons destinés à participer à au moins une fonction photométrique, une pièce monobloc (PM), réalisée dans un matériau transparent aux photons, et comprenant une face d'entrée (FE) permettant l'entrée dans une zone interne (ZI) des photons délivrés, une face arrière (FR) propre à réfléchir vers la zone interne (ZI) les photons délivrés qui sont entrés par la face d'entrée (FE), et une face avant (FV) constituant une face de sortie (FS) du bloc optique (BO) et propre à délivrer des photons sortants ayant été préalablement réfléchis par la face arrière (FR). Au moins les faces arrière (FR) et avant (FV) présentent des formes prédéfinies propres à rendre ensemble les photons sortants adaptés à la fonction photométrique.An optical element (EO) equips an optical block (BO) without ice and comprises a source (SP) delivering photons intended to participate in at least one photometric function, a one-piece piece (PM), made of a material transparent to photons, and comprising an input face (FE) allowing the input of an internal zone (ZI) of the delivered photons, a rear face (FR) adapted to reflect towards the internal zone (ZI) the delivered photons which are input by the face input (FE), and a front face (FV) constituting an output face (FS) of the optical block (BO) and adapted to deliver outgoing photons having previously been reflected by the rear face (FR). At least the rear (FR) and front (FV) faces have predefined shapes that make the outgoing photons together suitable for the photometric function.
