1. A tip part for an endoscope, said tip part comprising:
a vision receptor having a first lens and a vision sensor for providing an image from received light;
a casing with an internal surface supporting and contacting the first lens so that the casing substantially and directly maintains a position of the first lens in relation to another lens and/or in relation to the vision sensor;
a window made of a transparent material and positioned at a distal end of the tip part at least partly in front of the first lens, the window comprising a light source zone and a vision receptor zone;
a first light source;
an exterior housing having a distal or front end longitudinally opposite and spaced apart from a proximal or back end, the exterior housing having an exterior facing side wall extending from the front end to the back end and a front wall connected to the exterior facing side wall at the front end, the front wall and the exterior facing side wall defining an interior spacing, the exterior housing formed in one-piece with the casing and the front wall and accommodating the vision receptor and the first light source in the interior spacing, the front wall having an exterior surface and an interior surface opposite the exterior surface, the casing extending in the interior spacing from the interior surface of the front wall toward the back end; and
a light shield positioned between the vision receptor and the first light source so as to prevent ingress of stray light from the first light source into the vision receptor by optically shielding the vision receptor,
wherein the casing comprises a distal end embedded in the window at least in part between the light source zone and the vision receptor zone to prevent internal reflections in the window from reaching the vision receptor.
