Abstract
An optical system for a stereo video endoscope, a stereo video endoscope and a method for operating an optical system. The optical system includes a distal optical assembly and a proximal optical assembly with a left lens system channel and a right lens system channel. The distal optical assembly couples light incident from an object space into the left lens system channel and into the right lens system channel of the proximal optical assembly. The distal optical assembly is an optical assembly with an adjustable focal length, wherein a change in the focal length causes a displacement of an axis intersection point in the object space.
