Abstract (en)
[origin: EP2431658A2] The lens i.e. achromatic lens (22), has a spatial chamber formed between two partial lenses (24, 26) and filled with a translucent multifunctional medium (30) i.e. silicon, between the partial lenses enclosed along an outer circumference of the lens. The lenses are arranged behind one another in light passage direction. The medium achieves function of an optically activated part medium in a beam path of light passed through the lens, function of filling and sealing medium from a central edge to an outer edge of the lens and function of compensation medium out of the circumference. An independent claim is also included for a light module for a motor vehicle headlamp, comprising a light source.
