The invention relates to a tube for a surgical microscope. The tube has a base part, an intermediate part, which is pivotable about a rotational axis on the base part, and an ocular part which is pivotable about a rotational axis on the intermediate part. The imaging beam path is guided through the base part, the intermediate part and the pivotable ocular part. The tube has a tube lens system which transfers a parallel imaging beam paths into an intermediate image. The parallel imaging beam path enters via an opening in a connecting piece of the base part. The tube has a first displaceable mirror element which can be moved about the rotational axis on the base part. The tube lens system is a telesystem which has a lens unit having positive refractive power and a lens unit having negative refractive power.

Tube for a surgical microscope

A surgical microscope () has a viewing optic () which allows a viewing person to view the enlarged display of an object region () in a viewing area (). The viewing optic () has a continuously adjustable magnification system () with which a viewing optic adjusting unit () is associated. The surgical microscope () has an adjustable illuminating system (), which provides illuminating light () for the object region (), to illuminate the object region in an illuminated area () using illuminating light () of adjustable radiation intensity. An illumination system control unit () is provided in the surgical microscope (), the control unit being connected to the viewing optic adjusting unit () for receiving information as to the adjusted magnification of the viewing optic ().

A camera holder () is provided for fixing a camera () or a camcorder to an optical observation device. The holder () has a variable-length sleeve () with a first end configured to receive the camera objective and a second end configured to secure the sleeve () relative to the optical observation device. The holder () also has an adjusting device () fixed to the sleeve (). The adjusting device () has a pin for connection with a stand mating thread of a camera () and is configured to compensate for an offset between the stand mating thread and the camera objective. The adjusting device () enables the camera () to be positioned with respect to the sleeve and the optical observation device.

The invention relates to an arrangement for at least partially compensating a torque caused by gravitational forces acting on a mass body (), which is rotatably supported on an axis of rotation (). The arrangement includes a gas pressure spring () for providing a linear force. This linear force is transformed into a torque by means of a converter unit (). The mass body () and the converter unit () can be coupled to each other in a way which allows for adjusting the amplitude and the phase of a compensating torque.
