  • Publication number: 20240000296
    Abstract: A stereoscopic endoscope may comprise a first image capture sensor comprising a first surface and a second image capture sensor comprising a second surface. The endoscope also may comprise a first objective lens assembly to direct first light to the first surface. The first light extends along a first distal optical axis through the first objective lens assembly and extends along a first proximal optical axis after exiting. The first proximal optical axis intersects the first surface. The endoscope may also comprise a second objective lens assembly to direct second light to the second surface. The second light extends along a second distal optical axis through the second objective lens assembly and extends along a second proximal optical axis after exiting. The second proximal optical axis intersects the second surface. The first distal optical axis may be non-parallel to the second distal optical axis.
