Abstract

A field-correcting optical element configured to be arranged in an adaptive lighting device crosswise to light rays emitted by a plurality of light sources includes an entrance face through which light rays enter and an exit face through which these light rays exit. At least one segment of the entrance face is covered with an antireflection coating that is able to increase the transmittance of light rays through the optical element.
