Patent abstract
The invention relates to a device for shielding coherent electromagnetic radiation, especially laser radiation. The device comprises at least two partially converging faces (6, 7) between which two opposite openings (8, 9) are configured. The distance of the faces (6, 7) between the two openings (8, 9) varies to such an extent that the electromagnetic radiation is prevented from going from the one opening (8) straight through the other opening (9).
