The reflex image optical arrangement has a lens (5) fixed on the optical axis of a lamp (2) with prism optics to the right and left of the lens which deflect the lamp's light flow via a reflector (7) through the prisms (3,4) to prevent dazzling of the human eye. Successive contrast is generated by the optical change between the prisms and the dark field (6). The lens can be a biconvex, plane convex or concave convex collection lens, as a biconcave, plane concave or convex concave diversion lens according to optical requirements.
