## Abstract

The invention relates to a long-range optical device (1) with an observation beam path (8) and a graticule for aiming at a target, and with a laser rangefinder (15), wherein a transmitting beam path of a laser transmitter (16) runs at least partly in the observation beam path (8), and wherein in an objective housing (63) a joint is arranged and at least one lens of the objective (31) is mounted to be movable by means of the joint in the objective housing (63), and wherein the joint comprises a bearing housing (66) fixed in the objective housing (63) and a lens tube (64), and at an object-side end of the lens tube (64) a front objective lens system (61) of the objective (31) is arranged and an eyepiece side end of the lens tube (64) is mounted pivotably in the bearing housing (66).

## Claims

### Claim 1

A long-range optical device comprising:
