An instrument includes a hollow body with an internal diameter and an optoelectronic image recording system, which is arranged in an end region of the body and has a lens system on an image entrance side. The lens system has a cylindrical section and an image sensor. An external diameter of the cylindrical section is less than the internal diameter of the body, such that an interspace remains between an inner side of the body and an outer side of the lens system, providing access in the body for components. With a viewing direction of 0° to 90° from the optical axis of the lens system, a deflection prism is arranged on the image entrance side at the lens system, and has a section extending laterally beyond the external diameter of the cylindrical section. An image entrance plane of the image sensor runs approximately parallel to the optical axis. |
