Abstract

The invention relates to a long range optical device with at least a first visual optical path and a focusing device for focusing the at least first visual optical path. The long range optical device may also include a laser distance meter with a laser transmitter and a laser receiver, wherein a part of an optical path of the laser receiver extends in the at least first visual optical path to the objective lens. A region of the deflection of the optical path of the laser receiver out of the at least first visual optical path may be disposed on at least one optical component. The focusing device may be disposed between the at least one optical component for deflecting of the optical path of the laser receiver and the objective lens.

First claim

The invention claimed is:

1. A binocular comprising:
a first observation part with a first visual optical path with, in this order, a first objective lens, a first focusing device, a first prism erecting system, and a first ocular;
a second observation part with a second visual optical path with a second objective lens, a second focusing device, a second prism erecting system, and a second ocular,
wherein the first and second observation parts are connected to one another via a hinged bridge, and
wherein the first and second prism erecting system each comprises a roof prism and a deviation prism and a splitter prism, the splitter prism attached to a face of the deviation prism lying opposite to the roof prism, and with a partially transparent coating in between the deviation prism and the splitter prism acting as a beam splitting surface; and
a laser distance meter with a laser transmitter and a laser receiver and a display element,
wherein a part of an optical path of the laser receiver extends in the first visual optical path from the first objective lens over the first focusing device to the first prism erecting system and is split out of the first visual optical path at the beam splitting surface between the deviation prism and the splitter prism of the first prism erecting system,
wherein a part of the optical path of a display optics is merged with the second visual optical path at the beam splitting surface between the deviation prism and the splitter prism of the second prism erecting system, and
wherein an optical path of the laser transmitter is arranged separate from the first and second visual optical path as a third optical path.

2. The binocular, according to claim 1 , wherein the optical path of the laser transmitter can also be focused with the focusing device for the first and second visual optical path.

3. The binocular, according to claim 1 , wherein in each of the first visual optical path and the second visual optical path the beam splitting surface between the deviation prism and the splitter prism of the prism erecting system is disposed between an observer-side focal point of the objective lens and the focusing device or objective lens.

4. The binocular, according to claim 1 , wherein a control and evaluation device with at least one display element for displaying a sight mark and/or a measurement value of the laser distance meter is connected into the second visual optical path.

5. The binocular, according to claim 4 , wherein a remote transmission means is provided to run a wireless transmission to a display element and/or the control and evaluation device of a distance measured by the laser distance meter and/or at least one item of data, such as a value of the focus setting, a magnification factor, a brightness or temperature value.

6. The binocular, according to claim 4 , wherein the control and evaluation device is wirelessly connected via remote transmission means to an independent display element external to the observation device.

7. The binocular, according to claim 4 , wherein the display element is LED or LCD displays with individual activation of individual image-generating pixels.

8. The binocular, according to claim 1 , wherein another display element is disposed on an external face of the observation device.

9. The binocular, according to claim 1 , wherein a displacement motor is connected to the focusing device.

10. The binocular, according to claim 9 , wherein the control and evaluation unit is connected to the displacement motor.

11. The binocular, according to claim 1 , wherein the first observation parts and the second observation part are connected via two hinged bridges spaced apart from one another in the direction of the optical paths so that they can be displaced in terms of their relative position.

12. The binocular, according to claim 11 , wherein the first observation part and the second observation part each comprising one of the first visual optical path and the second visual optical path are connected via two hinged bridges with two separate joint pins spaced apart from one another in the direction of the optical paths along the observation direction so that they can be displaced relative to one another, between which a gap is left free which is laterally bounded by the observation parts.

13. The binocular, according to claim 12 , wherein the hinged bridge is connected at its two end regions facing the two observation parts via a joint to each of the two observation parts, the pivot axis of which extends approximately parallel with the longitudinal axes of the two observation parts.

14. The binocular, according to claim 11 , wherein three or more hinged bridges are provided.

15. The binocular, according to claim 11 , wherein a keel-shaped housing extension is disposed on at least one of the two observation parts.

16. The binocular, according to claim 15 , wherein the housing extension comprises an internal housing region for the device electronics.

17. The binocular, according to claim 11 , wherein the first observation part or the second observation part is designed as an independent long range optical device.
