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.

An auxiliary measuring instrument, configured to form together with a ground-based surveying device having range-and-direction measuring functionality, a system for surveying or staking out object points, wherein the auxiliary measuring instrument including a handheld main body of a defined length, and a man-machine interface, wherein the auxiliary measuring instrument is designed in a pen-like form and size and is configured to aim at an object point to be surveyed or staked out in a one-handed manner with a first end of the auxiliary measuring instrument and wherein a body is attached at a second end of the auxiliary measuring instrument, wherein the body is designed for optical-image-based determination of the position of the auxiliary measuring instrument by the surveying device.

Surveying system and auxiliary measuring device

A method comprising: setting up a stationary surveying device at a first known positioning in a surrounding area of the object; retrieving from a memory a set of object points of an object to be surveyed and/or to be marked; surveying and/or marking from a first positioning object points of the set of object points that can be surveyed and/or can be marked from the first positioning by means of the free beam, on the basis of a target direction; ascertaining missing object points of a set of object points; relocating the surveying device to a second, unknown positioning in the surrounding area of the object; automatically determining a second positioning by the surveying device on the basis of the knowledge of the first positioning, so that the second positioning is known; surveying and/or marking missing object points by means of the free beam from the second positioning.

Surveying system and auxiliary measuring instrument

A calibrating method and system for an auxiliary measuring instrument which is designed to form together with a ground-based, stationary, surveying device having range-and-direction measuring functionality, a total station, a system for surveying and/or staking out object points. The auxiliary measuring instrument including a body which has a code for determining the orientation by using a pivoting movement of the body about a resting contact end of the auxiliary measuring instrument.

An apparatus for inserting a measurement light beam which can be projected onto a target object, comprising a light-refracting component having an optical axis, and at least two mirrors for deflecting the measurement light beam, and an optical overall body consisting of at least one optically effective material, wherein the optical overall body is configured in such a way that the at least two mirrors are fitted inside or at the edge, in particular as a part, of the optical overall body, in such a way that the measurement light beam entering the optical overall body is offset parallel to the incident measurement light beam when emerging from the optical overall body, so that the emerging measurement light beam lies on the optical axis of the light-refracting component of the apparatus and is projected in this form onto the target object.

Insertion apparatus

A sensor module for connection to a handheld rangefinder instrument and for providing sensor data for the rangefinder instrument includes an electronic interface for connection to an applicable interface of the rangefinder instrument, and at least one electronic sensor component for generating the sensor data. A system for handheld measurement of distances to a surface region of an object includes a sensor module of this kind and a handheld rangefinder instrument having a first laser rangefinder. When the interfaces are connected to one another, the sensor module is configured for transmitting the sensor data to the rangefinder instrument, and the interfaces are configured for transmitting electric power from the rangefinder instrument to the sensor module, in which the sensor module is configured to operate the at least one sensor component by means of the electric power transmitted by the rangefinder instrument.

Sensor module for applications with handheld rangefinder instrument

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.

Some embodiments of the invention relate to a hand-held distance-measuring device, comprising a housing, a distance-measuring unit for measuring distances to spatial points along an emission direction in a space, an evaluating component, a dimensionally stable referencing support, and an angle-determining unit for determining an angle of rotation (a, between the housing and the referencing support. In some embodiments, the housing and the referencing support are designed in such a way and coordinated with each other in such a way that the referencing support can assume a passive position, in which the referencing support is inserted into an recess of the housing or is fastened such as to lie flatly against the housing. In some embodiments, the referencing support can assume a referencing position in which the referencing support is connected to the housing at a first end of the referencing support by means of a joint.
