Abstract

A micro-optical inspection arrangement comprises micro-focusing elements which are composite bodies consisting of a main part and an additional part and which have a reference focal length. The main parts are provided as micro-focusing element preforms, and the additional parts are formed from one or more functional coatings. The invention also relates to a method for producing such a micro-optical inspection arrangement and to a micro-optical displaying arrangement comprising the micro-optical inspection arrangement according to the invention and a microstructure arrangement, in particular a moiré magnification arrangement and a modulo magnification arrangement. The invention also relates to security elements and data carriers that have the micro-optical inspection arrangement according to the invention.
