Abstract: An optical device for a motor vehicle headlight for producing continuously closed light distribution. The optical device includes: light sources; collimators which are respectively associated with a light source; and a light guiding body, which has a light shaping structure and is formed from a plurality of interconnected facets. The facets respectively have an inclination to the main emission direction, wherein the spatial vector of a facet forms a horizontal and a vertical angle of inclination to the main emission direction. The inclinations of all facets are distributed such that the horizontal angles of inclination are respectively distributed around an expected value that corresponds to the maximum luminous intensity of the light distribution such that light that enters or leaves the light guiding body via facets that have horizontal and vertical angles of inclination corresponding to the expected value forms the maximum luminous intensity of the light distribution. The light shaping structure forms the light entry side and/or the light exit side of the light guiding body, wherein the facets are distributed substantially homogeneously on the light entry and/or exit sides in relation to their respective inclinations.
