An apparatus for generating and viewing an image of an item (95) against a reflective surface (94) with a light source (85), a camera (97) and operational electronics (98) installed on a single, common circuit board (99) located with a plane thereof along an exterior upright wall (102′) of a closed optics compartment (102). The light source faces a window element (103) of the closed optics compartment with a first light guide part (86) and directs light further into the optics compartment by means of a second light guide part (86′) located on the other side of the window element and aligned with the first light guide part (86). An optical unit is located in the optics compartment and comprises a light path extender (89, 90, 91), a light source input region, a lens unit (93), and at least one image detection output region. The light source input region comprises said first tubular light guide part (86) contacting the outside of the window (103), and the second tubular light guide part (86′) contacting the inside face of the window element (103) and aligned with the first light guide part (86), said second light guide part (86′) at a downstream end having a 45° inclined, first light redirecting mirror (87), and an output aperture with a light diffuser (88).
