Abstract:
1. A pair of range binoculars comprising: a first observing optical system, wherein the first observing optical system comprises: a second observing optical system separate from the first observing optical system, wherein the second observing optical system comprises: laser beam-emitting means for emitting a laser beam to measure a distance from an observation place to a target; a distance-measuring optical system for collimating the laser beam emitted by the laser beam-emitting means and sending the laser beam collimated by the distance-measuring means to the target, wherein the distance-measuring optical system is provided separate from the first observing optical system and the second observing optical system; laser beam-receiving means for receiving the laser beam reflected by the target; distance-determining means for determining a distance between the observation place and the target using a flight time of the laser beam taken from the laser beam-emitting means to the laser beam-receiving means; and measurement-displaying means for displaying the distance obtained by the distance-measuring means, wherein one of the first optical member and the second optical member is a beam splitter which transmits the laser beam, wherein the laser beam then deviates from an optical path of the observing optical system and enters the distance-determining means, wherein the beam splitter reflects the visible light, and wherein the reflected visible light enters the observing optical system.
