摘要
The optical device (10) has 2 successive lenses, used for increasing or reducing the beam profile of the light beam by respective factors in 2 directions perpendicular to the light propagation direction. A deflection mirror is positioned in the light beam path between the lenses for deflecting the light beam through an angle, the first lens and the deflection mirror mounted on a common transparent carrier through which the light beam passes to the second lens (20). An Independent claim for a method for manufacturing an optical device for geometric shaping of a light beam profile is also included.
