The present invention comprises a way to arrange the light path in a monocular, binocular or similar instrument (7), to obtain in practice an instrument as compact and ergonomical as possible, at the same time as best possible optical data are maintained and the internal mirrors (1-4) can be given smallest dimensions. The light path is located near a plane, but at least two (2; 3) of the image erecting mirrors are located on each side of this plane. The light from the objective (6) strikes these two mirrors (2; 3) in turn, and image tilt is eliminated by inclining the intersection line for said two mirrors (2; 3) to the plane. |
