Abstract
A sighting device couples a sight mark into a viewing beam path and is especially for a handheld weapon (), a bow or a pump gun. The sighting device includes an optical component () having a first optical coupling element () for coupling the sight mark from a sight mark source into the component () and having a second optical coupling element in the region of the viewing beam path for coupling the sight mark () out of the component () and into the viewing beam path. The second optical coupling element is configured as a diffractive structure (). The optical component () is configured to be totally reflective for guiding the sight mark beam in the interior of the optical component and is at least partially transmissive for the viewing beam paths in the region of the viewing beam path. In this way, a compact and lightweight illuminated sight is provided.
