Zusammenfassung:	The invention relates to a light guide (9) for an interface module, particularly for a vehicle interior, comprising a body consisting of a transparent or translucent material guiding light by reflection on the guiding walls (6) thereof, comprising: an internal diopter (δint) on one of the ends of the body consisting of a transparent or translucent material, which is to be oriented towards at least one light detector (11) or at least one light source (5); and an external diopter (δext) arranged on an end opposite the internal diopter (δint) of the body consisting of a transparent material. The external diopter comprises two separate transverse surfaces (S1, S2), with normals pointing in different directions for conjugating light between two separate portions (C1, C2) of the detection space on the one hand and the internal diopter (δint) on the other hand.
