| Zusammenfassung: | The transmitting device has a light source (12) and an optical device for focussing the light. The linear dimensions of the light-emitting surface of the light source are less than 500 micrometer. The optical device includes an aperture (14) whose linear opening dimensions are less than 3 mm. The distance in the beam direction between the aperture and the light emitting surface is at least 5 mm. |
