A camera shutter device having a shutter blade which moves abruptly between a first position, in which it covers a transmission zone present between the carriers, and a second position, in which it opens up the transmission zone. On the shutter blade, there is provided a slide body which includes a displaceable permanent magnet and which is guided on a linear guide, the ends of which are assigned a respective rotatable permanent magnet. By oppositely changing the polarization direction of the rotatable permanent magnets through 180°, the displaceable permanent magnet is pulled into the first or second position.

A transmitting device, containing an emitting device () and a scanning mirror (), which is deflectable about its center (MP) and is arranged in a housing () with a transparent cover element (). The cover element () is formed, at least in a coupling-out region (), by a section of a monocentric hemispherical shell (HK) with a center of curvature (K) and is arranged to cover the scanning mirror () in such a way that the center of curvature (K) of the hemispherical shell (HK) and the center (MP) of the scanning mirror () coincide.

A transmitting device, preferably containing at least two laser diodes and a scanning mirror, which is deflectable about its center (MP) and is arranged in a housing with a transparent cover element. The cover element is formed, at least in a coupling-out region, by a section of a monocentric hemispherical shell (HK) with a center of curvature (K) and is arranged to cover the scanning mirror in such a way that the center of curvature (K) of the hemispherical shell (HK) and the center (MP) of the scanning mirror coincide, and is formed in a coupling-in region by an optical block, comprising a toroidal entrance surface, in the special form of a cylindrical surface, at least one toroidal exit surface and at least two first mirror surfaces arranged between them, for deflecting and pre-collimating the laser beams.

A monocentric reception arrangement comprising an optical system (), in the spherical focal plane (BF) of which the imaged overall image of an object field is subdivided into partial images by field lenses () of a field lens array () arranged here and the partial beams in each case involved in a partial image are collimated by way of a downstream collimator lens () in each case onto in each case one receiver () of an optoelectronic receiver array (). An aperture stop is arranged in a plane of each receiver surface of one of the receivers (), the image of said aperture stop being the entrance pupil, in the center of which lies the common center of curvature (MP) of the spherical entrance surface () and the curvature of the field lens array (). Each partial beam illuminates one of the receiver surfaces with the same beam diameter.

An optical beam shaping unit for shaping a beam bundle. The optical beam shaping unit has at least one ball lens for shaping the beam bundle, wherein the ball lens allows a large portion of the light incident on the ball lens to pass through, and wherein the optical beam shaping unit has at least one optical unit which has a positive effective focal length and which is arranged in a beam path with the ball lens.

Rangefinder

A laser distance measuring device comprising a transmitter channel (), a receiver channel () and a dimensionally stable multilayer base printed circuit board (), with the transmitter channel () and the receiver channel () being mounted and symmetrically disposed one on each side of the base printed circuit board (), with the base printed circuit board () serving as a mechanical foundation, as an optical and electrical shield, as a carrier of electrical and optical connections and, optionally, as a heat conductor.

Compact laser rangefinder

An arrangement and a method for generating a plurality of optical axes which are oriented in a defined manner relative to one another in which the directions of the optical axes are defined by the reflection angles of a light bundle at plane mirror surfaces arranged in different ways. The object of the invention, to find a novel possibility for generating a plurality of optical axes oriented in a defined manner relative to one another using plane mirror surfaces which allows an accurate orientation of the optical axes independent from manufacturing tolerances of the components for holding the mirrors and a simple final adjustment, is met in that the plane mirror surfaces are arranged on the section face of spherical segments, and every spherical segment is embedded with its spherical cap in a recess of a base body, wherein the outside surface of the recess allows only those contact points between the spherical cap of the spherical segment and the recess which constitute an invariable pattern of contact points which is not dependent on the orientation of the mirror surface, and the spherical segments are rigidly fixed in the recesses of the base body by a connection layer after they have been adjusted corresponding to the optical axes to be aligned by means of a template.
