Abstract: A laser level comprising a first laser module and a second laser module, each comprising a laser diode and an optical unit, a holder arranging the first laser module and the second laser module in a fixed relative position, and a housing, in which the holder is suspended with a gimbal or ball joint. Each optical unit comprises a collimating lens arranged along the beam path following the laser diode, and configured for collimating a beam emitted by the laser diode; a pair of partially transmitting mirrors, each arranged along the beam path following the collimating lens, and configured for laterally reflecting less than half of the collimated beam in terms of the beam cross-section, and in terms of the beam intensity; and a cylindrical lens arranged along the beam path following the pair of partially transmitting mirrors, and configured for shaping the collimated beam into a fan beam.

Abstract: A geodetic instrument, e.g. a total station, laser scanner, laser tracker or laser level, for example for construction works. The geodetic instrument is separated into a static base part and a rotatable targeting part. The base part comprises a power unit for powering the geodetic instrument and the targeting part comprises a surveying and/or projection module for geodetic surveying and/or projection in a changeable target direction. Any change of the target direction is effected with the base part remaining static wherefore the targeting part is rotatable relative to the base part. The base part inertia is equal to or greater than the target part inertia.

Abstract: A geodetic instrument with a base module and a surveying or projection module. A processor for control of the instrument is situated in the base module. The surveying or projection module is rotatable about two axes by a drive unit of the base. The instrument comprises a mechanical interface connecting the surveying or projection module to the base module and an optical or electrical contact interface between the base module and the geodetic surveying or projection module. The interfaces are designed such that the surveying or projection module is mountable to the base module and dismountable from the base module by a user, whereby the geodetic instrument is designed for mounting of various surveying or projection modules of different geodetic type and execution of accordingly different geodetic surveying or projection functions.

Abstract: A laser distance meter consisting of an optical emitting path having an optical emitter and emitting optics and a receiving path having receiving optics and an optical detector. In this case, an optics mount completely optically isolates the emitting path and receiving path from one another and fixes the components thereof. The emitting optics and receiving optics are designed as plastic components transmissive to the measuring beams, and the optics mount is designed as a plastic component opaque to the measuring beams. The material composite of the emitting optics, the receiving optics, and the optics mount are designed as a 2-component injection molded part.
