Abstract
A stereoscopic endoscope system includes a combined system of a stereoscopic endoscope unit and a camera unit. The stereoscopic endoscope unit has an insertion part and an observation part. The insertion part includes an objective lens and a relay lens in order from an object side, where the objective lens has a pair of first optical system and a second optical system which are arranged in parallel in an insertion direction, and a third optical system arranged in the insertion direction. The first optical system and the second optical system are for a stereoscopic vision observation, and the optical system has a viewing angle larger than that of the first and the second optical systems for observing a wider range than a that of the stereoscopic vision observation. The relay lens is arranged on the camera unit side of the objective lens.
