TRANSPARENT OPTICAL ELEMENT HAVING DEFLECTING FACETS FOR IMAGE DOUBLICATION

The invention relates to an optical element (8) made of transparent or translucent material capable of transmitting light rays along an optical axis (10) and comprising an input portion (8 1) for light rays, an output portion (8 2) for light rays, remarkable in that the output portion (8 2) comprises at least one first facet (12, 16) inclined with respect to the optical axis (10) and capable of reflecting light rays transversely to said axis, and at least one second facet (14, 18) inclined with respect to the optical axis (10) and positioned transversely to the or at least one of the first inclined facets (12, 16), so as to reflect the rays coming from said or said first facets (12, 16) towards the output of the element. The invention also relates to a light module comprising such an optical element (8).
