1. A videoscope comprising:
a handle;
an insertion tube extending from the handle;
a tip part extending from the insertion tube and including:
a housing comprising an exterior housing and an interior housing,
the exterior housing including a distal end wall and a circumferentially extending side wall, the exterior housing having an interior space, a proximal opening, a camera stop surface, and a first light source stop surface;
the interior housing including a first tolerance compensator and a wall integrally formed in one piece with the first tolerance compensator and having a circumferentially extending closure surface, the first tolerance compensator extending distally from the wall into the interior space and having a first light source seat;
a camera assembly having an image sensor; and
a first light source including a light emitting surface, the light source sized and shaped to emit light through the light emitting surface along an optical axis thereof and illuminate a field of view of the camera assembly, the light emitting surface of the first light source positioned between the light source seat and the first light source stop surface without an air gap therebetween, the first light source stop surface traversed by the optical axis of the first light source,
wherein the first tolerance compensator is configured to move axially, during assembly, independently of the image sensor after the camera assembly contacts the camera stop surface to prevent further distal movement of the image sensor in the axial direction and to move the first light source axially, while the camera assembly does not move axially due to being in contact with the camera stop surface, until said movement is prevented by the first light source stop surface, such that an axial position of the first light source when the camera assembly contacts the camera stop surface is different than after said movement.
