Light beam swivel device

The innovation relates to a light beam pivoting device with a Deflection element that can be pivoted about two mutually perpendicular axes is.

From DE-OS 33 36 519 a light beam pivoting device is known in which the movement of a handle via a lever rod is transferred to the movement of a mirror with which a laser beam within the observation area of a surgical microscope is aligned. This known device is in accordance with the high requirements resulting from its use a laser with a surgical microscope for surgical fingertips result, very expensive. For other areas of application, such as the Irradiation with laser beams, lower requirements are sufficient.

The present innovation is therefore based on the object, a light beam pivoting device with a Umienkelement that by two Axes perpendicular to each other can be threatened to create that is as simple as possible in structure and yet easy to use.

The object is achieved according to the innovation in that the deflection element is firmly connected to a rotatable shaft that the rotatable "?" Shaft is mounted in a rotating sleeve. Which is rotatably mounted about its rotating sleeve axis arranged perpendicular to the shaft axis in a tube, that the shaft is passed through the rotating sleeve and cutouts in the tube and that the shaft is connected to a handle outside the tube.

In a particularly advantageous embodiment, the handle is as Handle ring executed, which only has an interruption for the exit of the light beam.

Further advantageous embodiments are based on the dependent
Claims and the explanations for the figures,

The innovation is explained in more detail below with reference to Figures la to 1c

explained. Show; j

Fig. La is a section through an embodiment; '

Fig. Ib a section along the section line Ib in Figure la and (

Fig. Ic a partial section along the section line Ic in Figure Ib * |

In the three figures, (11) denotes a mirror that points to a J

Mirror holder (12) is glued on. There is a 5 on the mirror holder (12)

two-part shaft (13), which can be rotated in the rotating sleeve (14) \

is stored and passed through this. The rotating sleeve (14) sits \

rotatable about its axis (14a) in the tube (15). It is useful to

Form the mirror holder (12) and the two-part shaft (13) so that OaR j

the shaft axis (13a) in the reflecting surface of the mirror (11) j

lies. [

The shaft (13) is through the cutouts (15a) through the tube (15) S.

passed through and firmly connected to the outside of the ring (16). This t

Ring can be tilted in the directions of the double arrow (16a) and rotated in the ι directions of the double arrow (16b). This will make the
Mirror (11) around the shaft axis (13a) and around the rotating sleeve axis (14a)
so that the light beam reflected by it is within a <.- i>
specific area can be swiveled in any direction.

In the rotating sleeve (14) is a lens (17) and a window (18)
used. Of course, instead of the lens (17), a
Window and instead of the window (18) a lens according to the
optical requirements are used. Through the lenses or windows
and the cover (19), the rotating sleeve is closed in a dust-tight manner. In the
Rotary sleeve (14) sit in a bore two pins (20) and (22) and

a spring (21), which the rotary movement of the rotary sleeve (14) in the tube (15) and the shaft (13) in the rotating sleeve (14) brake so that the Mirror (11) cannot be moved by gravity or vibrations adjustedi

The deflecting element can, in addition to that shown in the figures Mirror (11) also consist of a reflection prism, e.g. from a right-angled prism, the hypotenuse of which is used as a reflective surface.

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