Abstract
A device for collimating a light radiation field of a light source (L) having a beam characteristic which is different in a first plane (FAC) from that of a second plane (SAC). The device comprises at least one first collimating lens (10) and a second collimating lens (20). The device has an additional optical element (30) in order to collimate the light radiation field in different planes to the first and to the second plane.
