An enclosure assembly for a camera is designed to be mounted on the frame of an optical inspection apparatus for scanning the profile of a surface of an article moving along a travel path axis, the profile being associated with a reference axis orthogonal to a reference plane parallel to the travel path axis. The camera is part of a profile sensor unit and has an optical sensing field directed toward the travel path axis to define a scanning zone associated with the surface as intersected by the optical sensing field, the profile unit further having a laser source directing at angle with the optical sensing field a fan-shaped laser beam toward the scanning zone to define an associated scanning plane transverse to the travel path axis, to generate sensor output data related the profile of the article surface. The enclosure assembly comprises an enclosure body secured to the apparatus frame and including a front end wall provided with an opening protected by an optical element made of light transparent material, and a device for mounting the camera within the enclosure body such that the camera has its optical sensing field directed toward the opening. The enclosure assembly further comprises a device mechanically coupled to the enclosure body for displacing thereof in a direction perpendicular to the profile reference axis and parallel to the scanning plane to adjust the position of the optical sensing field with respect to the scanning plane.
