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 tube for an optical observation device, in particular for a microscope, with a viewing level that is linearly variable in length and/or height, wherein the tube has an optical light path, in which at least two optical elements are disposed, for example, deflecting elements. The tube can be designed, for example, as a swing-in tube, with a base part, wherein a deflecting element is disposed in the base part so that it can rotate around an axis of rotation, and with an eyepiece support that can swing in relative to the base part, wherein a deflecting element is disposed in the eyepiece support so that it can rotate around an axis of rotation. The optical elements may be disposed so that they can move independently of one another in the optical light path.

Tube for an observation device

A tube of a surgical microscope has a base part, intermediate part pivotable about a rotational axis on the base part, and an ocular part pivotable about a rotational axis on the intermediate part. The imaging beam path is guided through the base part, intermediate part and pivotable ocular part. The tube has a tube lens system which transfers a parallel imaging beam path 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 movable about the rotational axis on the base part. The tube has a further displaceable mirror element movable on the intermediate part about the rotational axis. The first mirror element directs the imaging beam path to the further mirror element. The first mirror element and further mirror element are mounted in the imaging beam path between a lens unit having positive refractive power and a lens unit having negative refractive power.
