Abstract: In an arrangement to optically illuminate and/or to perform measurements in a sample stream through a flange which is arranged in the sample stream and closes off a hollow space against the sample stream, there is a continuous loss of material due to abrasion of wall particles, and the flange therefore has to be exchanged on a regular basis. The invention has the purpose of reducing the wear on the flange. To meet this objective, a part of the wall extending along a closed loop around the hollow space (3) consists of an elastomeric body (2.3). This concept makes it possible for the flange or at least for a part of the flange to elastically back away under a concentrated load. Thus, the rate of abrasion of the wall by the sample stream is reduced, because a large part of the incoming energy is converted to heat in the elastomeric body.
