The probe has a distal terminal end (11) including an image sensor (1) with a rectangular light-sensitive surface (2) associated with an objective. The objective transmits a light beam including a proximal part (17) that is identical to a light-sensitive surface of the image sensor. The objective comprises a distal lens (9), which is produced from a circular lens (6), and a specific parts of the circular lenses that are not passed through by light rays transmitted by the objective to the light-sensitive surface, are removed to reduce lateral dimensions of a distal part of the objective.
