Optics for slim style head lighting

An optical system comprising:

• a collimator configured to receive light emissions and generate a collimated beam;
• an etendue re-shaper configured to split the collimated beam into at least two beam parts and arrange the at least two beam parts adjacent to each other to generate an adjacent beam part arrangement;
• and
• an optical relay system configured to map a light distribution of a beam part of the at least two beam parts to a same plane as an exit plane of the etendue re-shaper, the optical relay system comprising an absorber configured to adjust a flux in the beam part of the collimated beam to match an illuminance of the beam part with an illuminance of a second beam part of the collimated beam at an exit plane of the etendue re-shaper.
