1. A long-range optical device comprising:
at least one objective and at least one eyepiece and at least one prism reversing system with a roof prism and a deflecting prism, through which a first observation beam path is formed;
a display beam splitter formed by the deflecting prism;
an illuminating beam splitter;
an opto-electronic display, for displaying variable data or a target mark; and
a light source, wherein light of the light source is reflected by the illuminating beam splitter to the opto-electronic display and reflected by the opto-electronic display defining reflected image information to be displayed, the reflected image information passing through the illuminating beam splitter and is coupled into the first observation beam path at an interface of the deflecting prism, an image produced on the opto-electronic display being superimposed with an image of a remote object in the first observation beam path by the display beam splitter, and
wherein between the illuminating beam splitter and the opto-electronic display a wave plate is arranged, wherein the wave plate is formed by a λ/4 plate.
