An endoscope for stereoscopic viewing of surgical procedures, consisting of two solid-state cameras and a bundle of illuminating optic fibers. The width of the optic fiber bundle is approximately equal to that of the endoscope thereby maximizing the amount of light which the bundle can provide. The viewing cameras can be separated to a distance greater than the width of the sheath for enhanced depth perception and greater light delivery, and withdrawn into the sheath for insertion and withdrawal of the endoscope from the surgical cavity. The orientation of the cameras can be controlled to provide off-axis viewing.
