ABSTRACT:
An endoscope has an insertion section extended from an operation section. An observation window and an illumination window are formed in the distal end of the insertion section. The observation window is positioned nearer the distal end of the insertion section than the illumination window. A light guide extends from the illumination window through the insertion section and guides light emitted from a light source to emit the light from the illumination window. An objective lens system is arranged in the insertion section and optically connected to the observation window. An optical image of light, incident on the system through the observation window, is formed by the system. A solid-state image sensor is arranged in the insertion section and positioned nearer the distal end of the insertion section than the end of the light guide at the illumination window side. The sensor converts the optical image to an electrical signal and transmits it to a control unit.
