A multiple axis laser emitter ( ) comprising an optical beam splitter ( ) having at least two reflectively coated mirror surfaces ( ) oriented perpendicular to each other and each oriented at an angle of 45&deg; to a collimated main beam (H) of a laser light source ( ) and at an angle of 90&deg; to each other, wherein, in the beam path, an optical wedge ( ) is arranged downstream to at least one of the component beams (Ta, Tb, Tc, Td) deflected by the mirror surfaces ( ) at an angle of 90&deg; to the main beam (H).

Multiple-axis laser emitter with optical beam splitter

A laser arrangement for use in a multi-beam laser sighting mechanism, which comprises a light source for producing at least one primary laser beam bundle and an optical beam divider with reflecting surfaces, by which at least one primary laser beam bundle can be split into at least two partial beam bundles, which extend perpendicularly to one another. The light source comprises two semiconductor lasers including light-emitting surfaces which have a longitudinal extent and a transverse extent, which are in a ratio of about 2.5:1 to about 4:1 to one another. The light-emitting surfaces of the semiconductor lasers are disposed so that the longitudinal extents of the light-emitting surfaces are rotated at an angle of 90&deg; to one another and the primary beam bundles, which are produced by the two semiconductor lasers, can be superimposed before or at the beam divider.

Laser arrangement for a multi-beam laser sighting mechanism

A self-leveling device having a modular unitary suspension ( ) for a measurement system carrier ( ) of a tiltable housing ( ), with the carrier oscillating freely in at least one direction, and the device being distinguished by a flexible connector assembly ( ) formed of rubber-like elastic material and situated between two mounting structures ( ). The connector assembly is designed as a compact structural component and forms a rotationally symmetrical flexural moment at least in one axial mid region of flexure.

Self-leveling device

A beamsplitter for splitting a light beam in a plurality of separate beams, and having at least two reflecting surfaces (,) inclined each at an angle of 45&deg; to a propagation direction of a collimated primary light beam (P) emitted by a light source (,), forming a right angle with each other, located at a same distance from a collimator (,) for collimating the primary light beam, and extending into a path of the collimated light beam for emitting two output beams; and a light passage (,) provided in a space between the reflecting surfaces (,) and extending substantially symmetrical to an optical axis of the collimator for enabling passing through the passage a central portion (M) of the collimated primary light beam; and an alignment tool including the beamsplitter.
