Patent ID: 8149507

Claim:
A binocular for viewing an object, the binocular comprising: first and second tubes conjointly defining a distance therebetween; first and second Abbe-König prism systems arranged in said first and second tubes, respectively, for image inverting a visual viewing beam in the tube corresponding thereto; each of said Abbe-König prism systems including an isosceles prism and a roof prism disposed one behind the other; each of said tubes having a forward lens forward of the Abbe-König prism system and a rearward lens rearward of the Abbe-König prism system; said forward and rearward lenses of each of said tubes defining an optical axis passing through the corresponding Abbe-König prism system disposed therebetween; each one of said Abbe-König prism systems being configured to offset the corresponding optical axis passing therethrough in a range from a zero offset to a predetermined offset value; a laser transmitter defining a laser beam outgoing therefrom to said object and being disposed in said first tube; a laser receiver being disposed in said second tube; said laser receiver being assigned to said laser transmitter with said laser beam being reflected at said object to become an incoming laser beam to said laser receiver; a folding bridge connecting said first and second tubes so as to permit varying said distance between said first and second tubes and therewith varying a spacing between said laser transmitter and said laser receiver parallel to each other; one of said isosceles prism and said roof prism of each of said Abbe-König prism systems defining a splitter arrangement for splitting the visual viewing beam and the laser beam, which run part way in common in the corresponding tube, into separate beams; one of said isosceles prism and said roof prism being configured to include a splitter layer defining said splitter arrangement for splitting the visual viewing beam and the laser beam into separate beams; wherein one of said isosceles prism and said roof prism comprises a first component prism and a second component prism conjointly defining a partition interface whereat said first and second component prisms are connected to each other; and, a coating disposed at said interface to define said splitter layer for splitting said visual viewing beam and said laser beam, which run part way in common in the corresponding tube, into separate beams by reflection of a defined wavelength range.
