摘要 |
<p>The attenuator is intended for a collimated laser beam and is characterised in that it comprises a holographic dichromat-gelatine plate (4), which is arranged adjustably in a housing (3) such that the laser beam (1) is incident upon it at a virtually perpendicular angle of incidence, and a diaphragm (10 to 12), which is arranged behind the plate and has a central hole (11) for the free passage of the beam. The diaphragm surface facing this plate is covered with an absorbing layer (12). <IMAGE></p> |
