Device for transmitting optical signals

摘要

The device has an optical transmission unit (1) and an optical assembly for conditioning a light beam transmitted by the unit. A light trap (11), diffractive element (24) and a metallizing layer (25) are arranged for weakening of intensity of the beam within an area of an optical-axis of the device. The optical assembly has a collimator (2) for performing beam widening in a direction of the beam that is emitted by the unit. The metallizing layer is arranged within the range of the optical axis of optical elements (21-23) e.g. lore lenses, of the collimator.
