Optical device for representing a central image ( 10 ) of an object ( 1 ) and at least one lateral image ( 11, 12, 13, 14 ) of the same object ( 1 ), with the length of the real optical path of said central image ( 10 ) being different from the length of the real optical path of said at least one lateral image ( 11, 12, 13, 14 ) and the length of the apparent optical path of said central image ( 10 ) being equal to the length of the apparent optical path of said at least one lateral image ( 11, 12, 13, 14 ), and module for the optical inspection of objects comprising such an optical device and an optical system ( 7 ) allowing a central image ( 10 ) of the object ( 1 ) and at least one lateral image ( 11, 12, 13, 14 ) of this same object ( 1 ) to be captured simultaneously. The apparent optical paths of the central image ( 10 ) and of the lateral image ( 11, 12, 13, 14 ) being identical, these two images can be captured and correctly focussed simultaneously by a same viewing system ( 7 ).
