Distance measuring device and surveying system

A distance-measuring device for contactless measurement of a distance to an object, the device comprising:

• a housing;
• a measurer utilizing an optical measuring beam and arranged in the housing, the measurer capable of measuring the distance to the target object contactlessly, the measurer including:
• a radiation unit,
• an optical unit with optical elements including:
• a transmitting and receiving lens system,
• an optical transmitting path with an optical axis for emitting the measuring beam onto the target object, and
• an optical receiving path with a further optical axis for receiving the measuring beam reflected and/or scattered by the target object,
• at least one of the optical elements being movable and influencing the optical transmitting path and movable relative to an initial position;
• and
• a motion sensor configured to detect a movement of the housing during the measurement,
• the at least one movable optical element movable out of an initial position into a variable compensation position to stabilize the transmitting path at a spatially fixed position within a range of a compensation of the movement of the housing during the measurement,
• wherein the transmitting path runs biaxially to the receiving path via an output element of the transmitting lens system, and the movable optical element is configured in the form of the output element.
