Abstract: The invention relates to binoculars and a method for adjusting an interpupillary distance of binoculars, comprising a first housing half having a first eyepiece with a first optical axis, a second housing half having a second eyepiece with a second optical axis, wherein the distance of the first optical axis to the second optical axis defines an interpupillary distance and wherein the first housing half and the second housing half are hingedly connected to each other by means of at least one folding bridge and wherein the folding bridge comprises a first folding bridge portio coupled with the first housing half and a second folding bridge portion coupled with the second housing half and wherein the interpupillary distance may be changed by pivoting the two housing halves and wherein a detection device is formed, by means of which the interpupillary distance may be determined.

Abstract: The invention relates to a rangefinder for a telescope having a transmitter and a transmission beam path and having a first receiver and a first receiver beam path, wherein the first receiver beam path extends at least partially in a first observation beam path of the telescope. The rangefinder additionally comprises a second receiver with a second receiver beam path which is aligned in parallel to the first transmission beam path, and which is arranged at a distance from the first observation beam path of the telescope.
