Abstract
A stereoscopic-vision endoscope includes an objective optical system, a relay optical system, a first lens unit, a light-beam splitting element, a second lens unit, and an image sensor. An intermediate image, a first image, and a second image are formed in a common optical path, a first optical path, and a second optical path respectively. The light-beam splitting element has a surface of incidence and a surface of emergence. A first light ray which passes through the intermediate image and reaches first image and a second light ray which passes through the intermediate image and reaches the second image are refracted to be away from an optical axis of the common optical path on the surface of incidence, as well as are refracted to be closer to the optical axis of the common optical path on the surface of emergence.
