The invention relates to a motor vehicle headlamp (100) containing an ellipsoid reflector (130), which allows light coupled in from a light source (100) to exit through a reflector light exit opening (132), a collimator (140) and a projection optical unit (160). The collimator (140) is designed to collimate the incident light beam coming from the ellipsoid reflector (130) and to direct the same toward a first image plane (170). The projection optical unit (160) projects a light image produced by the light beam in the emission direction of the motor vehicle headlamp (100) in accordance with a second image plane (180) of the projection optical unit (160). The first image plane (170) and the second image plane (180) intersect or overlap with one another. In the beam path of the light beam, an optical element (150) having at least one optically active edge (151) is arranged between the collimator (140) and the projection optical unit (160) in such a way that the first and/or second image plane (170, 180) runs through the optical element (150), in Order to mask a part of the light beam and to guide another part to the projection optical unit (160).
