Abstract
The optical sighting device makes it possible to increase the quality of ical transmission by preventing turbulences from forming in the field of vision at high speed, by means of an airstream-deflecting device which is mounted in the turbulence formation zone and which has a profile in the form of a stem-post to dispel the air-streams laterally. In the case of transparent plane wall via which vision takes place in this zone, the deflecting device can consist of an attached plates which is connected to or located in the vicinity of the wall.
