Abstract

A lens for a distal end of an optical channel of an endoscope shaft is provided, wherein the lens defines an outer side and an inner side as well as a circumferential surface connecting the two sides, wherein a light-absorbing coating is applied to the circumferential surface and an area of the inner side connected thereto, and wherein a solderable layer is applied to the light-absorbing coating in the area of the circumferential surface with the result that the lens can be soldered in the distal end such that the distal end is sealed.
