Abstract
A tip part for an endoscope has a vision receptor having a vision sensor for providing an image from received light, a first lens, and a casing, the casing supporting the first lens so that the casing substantially maintains a position of the first lens in relation to the vision sensor; a first light source; an exterior housing; 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 is formed integrally with the exterior housing so that the casing also substantially maintains the first lens in a position in relation to the exterior housing.
