An optical assembly includes a volume grating configured to influence a beam direction of at least one light beam, and a switching device arranged in a beam path upstream of the volume grating. The switching device is configured to switch the beam direction and/or beam position of the at least one light beam from a first beam direction and/or beam position, in which the at least one light beam does not impinge on the volume grating at an acceptance angle of the volume grating, to a second beam direction and/or beam position, in which the at least one light beam impinges on the volume grating at the acceptance angle, and/or vice versa.

A device for holding filters for a microscope includes a filter wheel () rotatable about an axis of rotation () and a drive unit () for rotating the filter wheel (). The filter wheel () comprises a basic body () rotatable about the axis of rotation () and at least one segment (-) selectively connectable to the basic body. The segment (-) comprises at least two housing areas () each holding at least one filter (). Another housing area may provide a transmission range () for unfiltered transmission of light. A second rotatable filter wheel may be arranged at a location displaced along the axis of rotation relative to the filter wheel, and may have its own respective transmission range for unfiltered transmission of light, whereby a filter on either filter wheel may be aligned with the transmission range on the other filter wheel.

A device for deflecting a light beam in two different directions includes a mirror and a first rotating actuator element configured to rotate about a first axis as a function of a first actuation signal. A second rotating actuator element is disposed opposite to the first rotating actuator element along the first axis and configured to rotate about the first axis as a function of a second actuation signal. A first spring element is connected to the first rotating actuator element and, off-axially with respect to the first axis at a predetermined first distance thereto, to the mirror in a rest position of the mirror. A second spring element is connected to the second rotating actuator element and to the mirror.

An apparatus for damping sound in the optical beam path of a microscope, having an acoustic insulation housing for encapsulating a sound-emitting component, preferably a rapidly moving or oscillating beam deflection means, in particular a resonantly oscillating mirror, the housing comprising at least one optical entrance/exit opening, is characterized in that the housing, preferably the opening of the housing, is embodied and/or configured in such a way that the sound otherwise emerging from the housing is largely extinguished by destructive interference without thereby influencing the optical beam. A microscope having a corresponding apparatus is furthermore claimed.

Disclosed is a device for adjusting an optical fiber () or an optical fiber bundle relative to a coupling point. Said device comprises a holding apparatus () for the fiber/s () and a mechanism () for positioning the fiber/s () in said holding apparatus (). The positioning mechanism () is provided with at least two positioning members () which act upon the fiber/s () at different angles, the position of the fiber/s () relative to the holding apparatus () being modifiable by actuating said at least two positioning members (). The inventive device is characterized in that the positioning members () which are effective at different angles are disposed next to each other in the holding apparatus () in order to be actuated from one side while at least one of the positioning members () acts upon the fiber/s () via a lever assembly ().
