ABSTRACT:
The invention relates to an image transmission system for endoscopes and similar viewing tubes with at least one rod lens and at least one additional lens system. In order to produce an image transmission system of simple and economical construction, it is proposed in accordance with the invention that the minimum of one rod lens should be constructed as a plano-convex lens whose length corresponds to the curvature radius of its convex terminal surface. In addition, the invention relates to a process for producing a rod lens for an image transmission system as well as an endoscope equipped with such an image transmission system.
