Binocular

ababBinoculars have two tubes connected to each other via a folding bridge and an Abbe-König prism system is arranged in each tube and the Abbe-König prism systems are provided for image reversal of respective visual viewing beam paths. Each Abbe-König system includes an isosceles prism and a roof prism adjacent thereto. A laser transmitter in the first tube and a corresponding laser receiver in the second tube can be changed in parallel with respect to the distance to each other by means of the folding bridge. One of the two prisms of each Abbe-König prism system is configured with a splitter layer (″) or is connected via a cement layer for splitting the viewing beam and laser beam into separate beams with the beams running part way in common in the respective tubes.
