| 摘要 |
The invention describes a long-range optical device (1) with two observation parts (3, 4) and a first observation beam path (11; 12) and a measurement beam path (25), in which the two observation parts (3,4) are arranged essentially parallel next to each other and spaced a predefinable distance (10) apart via at least one connection element (7). In a plan view of the device 1 with respect to a plane, in which the longitudinal axes (8, 9) of the observation parts (3, 4) are arranged, the sub-regions of the observation parts (3, 4) facing each other lie directly opposite each other over a length aligned parallel to the longitudinal axis (8, 9) of the observation parts (3, 4) of 20% to 90%, preferably 30% to 80% of a length (24) of the observation parts (3, 4). In addition, the observation beam path (11, 12) and the measurement beam path (25) are arranged outside the sub-regions (22, 23) of the observation parts (3, 4).
