Abstract
A binocular comprising a housing and a pair of first and second optical systems positioned on each side of a central line. Each optical system includes an object lens and ocular lens arranged at a front part and at a rear part of the housing respectively. Further, a light admitting window is placed on the central line between the first and second optical systems for admitting light from an object. A detection module, provided independently of the first and second optical systems is used to output electrical signals which represent the distance to the object. The detection module may include an optical path deflecting means for z-shapely deflecting the light from the light admitting window and for directing the light to a sensor. The binocular is compact and has a hand grip that is designed in order to be holdable and focusable by the use of a single hand.
