Abstract

An optical system for a motor vehicle headlight, wherein the system includes at least two optical elements, including a light coupling area, a light decoupling area, a lateral surface which delimits the optical element and has an optically effective aperture edge for forming a bright/dark boundary in a far-field light distribution producible with the optical system. The system includes at least two anterior optics, wherein an anterior optic is associated with each optical element. The first anterior optic and first optical element are configured to produce a first far-field light distribution, wherein the second anterior optic and second optical element are configured to produce a second far-field light distribution, which lies below the bright/dark boundary of the first far-field light distribution.
