  • Patent number: 10983330
    Abstract: A 3D video endoscope has a shaft which has the form of a flexible or rigid elongated hollow body, a first image sensor, a second image sensor, a first optical channel which comprises a first objective lens and a first optical image guiding system which forwards the image captured by the first objective lens to the first image sensor, a second optical channel which comprises a second objective lens and a second optical image guiding system which forwards the image captured by the second objective lens to the second image sensor. The first optical channel and second optical channel are substantially arranged in the shaft. The first optical channel has a first diaphragm which reduces the aperture of the first optical channel compared to the aperture of the second optical channel. Apart from the first diaphragm, the first optical channel and the second optical channel are structured identically.
