Optisches Beobachtungsgerät

摘要

Disclosed is an optical device with at least one lens and at least one swivelling observation tube, exhibiting the following characteristics: the observation tube comprises a base section (BT), which is fixedly connected to the optical device, and an eyepiece carrier which rolls along the arc of a circle so that swivelling can occur on the base section; a first rotatable reflecting mirror whose rotational axis (SDA1) cuts the optical axis of the lens (OB) at a 90 DEG angle and which is forcibly rotated by the movement of the eyepiece carrier on the base section; a second rotatable reflecting mirror is arranged in the eyepiece carrier (OT), whose rotational axis (SDA2) cuts the optical axis of the lens (OB) which is deflected by the first reflecting mirror at an angle of 90 DEG and which is forcibly rotated by the movement of the eyepiece carrier on the base section.
