The range finder is of the type for transmitting and receiving a modulated beam of light for the distance determination to a remote reflector and has an integrated sighting telescope for sighting the reflector or some other target. The coaxial transmitting and receiving optical system and the sighting telescope have a common optical axis. A beam deflector which deflects into the optical axis the transmitting beam coming from an infra-red radiation-emitting source is arranged in the vicinity of the position at which there is an intermediate image formation of the transmitting beam path. A dielectric coating system which is permeable by visible light is arranged approximately perpendicular to the common optical axis. It is on one side bounded by air and is arranged in such a way that the transmitting beam from the beam deflector strikes the coating system in an almost perpendicular manner.
