The innovation relates to a light beam pivoting device a deflection element, which around two mutually perpendicular Axes is pivotable and which via a rotatable shaft with a handle is connected, the rotatable shaft with bearings is passed through a rotating sleeve, which is arranged around its rotating sleeve neck, which is arranged perpendicular to the shaft 3Gh.se, in a tube is rotatably mounted.

From the Di £ - G 85 35 100 a light bar is a pivoting device known / with which a mirror can be rotated around two mutually perpendicular directions * The mirror is also included for this fixedly connected to a rotatable shaft which is mounted in a rotating sleeve which is arranged around its axis perpendicular to the shaft Rotary sleeve axis is rotatably mounted in a tube. The shaft goes out through the rotating sleeve and cutouts in the tube and is connected to a grip ring outside the tube. As a result of the necessary cutouts in the tube, the rotation of the mirror is around the rotating sleeve axis or the tube axis limited. This is a disadvantage for some areas of application.

The present innovation is therefore based on the object to create a light beam pivoting device in which the Rotational movement of the deflecting element about the rotating sleeve axis or the tube axis is not limited. The task at hand will be solved according to the innovation in that the rotary cap is mounted outside the bearings of the rotatable shaft in the tube.

In an advantageous embodiment, the rotating sleeve is through Lenses and / or windows for the incoming and outgoing light beam and sealed dust-tight by a cover.

In a particularly advantageous embodiment, an additional lens is through a sliding member in the direction of the rotary sleeve

axis shifting bear, weaving the «'Scin ebe« tjC ie «ci at one end in the Rotary sleeve and is mounted in the tube at the other end.

Further advantageous embodiments can be found in the dependent Claims and the explanations for the figures.

The innovation is explained in more detail below with reference to FIGS. 1a and 1b. Show:

1a shows a section through an exemplary embodiment;

FIG. 1b shows a section along the section line 1b in FIG. 1a.

In both figures, (11) denotes a mirror which is glued onto a mirror holder (12) and which is in the Direction (10) deflects incident light. On the mirror holder (12) a two-part shaft (13) is attached, which is passed through the bearings (14b, 14c) of a rotary sleeve (14). The rotating sleeve is around its axis (14a), which is aligned with the direction (10) of the incident light, together with the shaft (13) and the mirror (11) rotatable and is for this purpose mounted outside the bearings (14b) and (14c) in the tube (15), whereby through the Relatively far apart bearing surfaces (14d) and (14e) a sufficiently stable guide is provided. The rotating sleeve (14) is held in place by a tenon screw in the tube (15) (15a), which slides with its pin in the groove (14f), secured against movements in the direction of its axis (14a).

It is useful to use the mirror holder (12) and the two-part Form shaft (13) so that the shaft axis (13a) in the reflective surface of the mirror (11). The wave (13) is firmly connected to a ring (16). This ring has an interruption (16c) for the exit of the light beam and can be tilted in the directions of the double arrow (16a) and rotated in the directions of the double arrow (16b). This will the mirror (11) is tilted about the axis (13a) and rotated about the axis of the rotating sleeve (14a). By storing the two-part

of the rotating sleeve (14) in the tube <15>, the rotation of the mirror (11) about the axis of rotation (I4ä) is not limited »

A lens (17) and a window (18) are inserted into the rotating sleeve (14). Of course, a window can also be used instead of the lens (17) and a lens instead of the window (18) according to the optical requirements. The rotating sleeve is closed dust-tight by the lenses or window and the cover (19).

In a particularly advantageous embodiment, a further lens (20) is arranged displaceably in the direction of the rotary sleeve axis (14a). It sits in the sliding member (21), which is mounted at one end in the rotating sleeve (14) and at the other end in the tube (15). The sliding member (21) is with the handle tube (22) is connected via the screw (22a) which slides into the slot (15b) of the tube (15). The Lentils (17) and (20) together form a zoom system with which e.g. Adjust the focus of a laser to different distances leaves.

Instead of the mirror (11) shown in the figures, the deflecting element can also consist of a reflection prism, e.g. from a right-angled prism whose hypotenuse is called reflective surface is used.

The innovation described can be used both for laser beams and for other light beams. A particular advantage is that, in spite of the simple structure, the reflected light beam is pivoted in two mutually perpendicular directions with a single operating element, and one-handed operation is therefore possible.
