Abstract

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.
