ABSTRACT:
Disclosed is a pair of range binoculars that, when the pupil distance is adjusted, is free from a deviation of the optical axes and undesirable influences on the electronic parts resulting from vibration caused by the adjustment, is capable to show the measured distance in such a way as the user can see it easily without making the system complicated, and secures the brightness of the visual field where the measured distance is displayed. The range binoculars are characterized in that a main case and an attached case contain a pair of left and right observation optical systems and the pupil distance is adjusted by turning only the attached case, and that the main case accommodates laser range-finding means, and measured distance displaying means comprising LCD means for displaying a distance measured by said laser range-finding means and a displaying optical system for projecting the distance displayed by said LCD means on the reticle so that the distance is shown at a rim of the visual field.
