FIELD: physics, optics.
SUBSTANCE: described is a security element for a counterfeit protected article, having an upper side and a lower side, as well as one or more imaging optical systems, each forming an enlarged image of the associated object only in the space before the upper side of the security element. One optical system or at least one of the optical systems has multiple reflective imaging microelements arranged in two-dimensional space in the form of a first drawing, said microelements being in the form of concave micromirrors. The object associated with the optical system is in the form of a microrelief object formed by multiple microrelief structures which are arranged in the form of a microrelief drawing, matched with the first drawing such that the reflective imaging microelements form an enlarged image of the microrelief object in the space before the upper side of the security element, which has at its upper side and its lower side an adhesive layer which enables to embed the security element into the counterfeit protected article with adhesion thereof to the upper side and the lower side of the security element.
EFFECT: improved security.
