Optic structure for endoscope, has mechanically movable lens which overlays major ray path and generates another ray path that lies outside of optic structure, when set in predetermined position

摘要

The optic structure (1) includes a mechanically movable lens (2) which overlays a major ray path (3) and generates another ray path (4) that lies outside of the optic structure, when set in a predetermined position (2b). The other ray path has an optic axis which forms a predetermined angle relative to the optical axis of the major ray path.
