The armored glass is a composite having at least one opto-ceramic layer having a front side and a rear side and a film of a transparent material disposed on the front and/or rear side of the opto-ceramic layer and integrally connected to the opto-ceramic layer so that the transparency of the composite is greater than the transparency of the opto-ceramic layer alone. The film of the transparent material renders roughnesses of the front and/or rear side of the opto-ceramic layer substantially optically ineffective.

Abstract: An exemplary embodiment provides transparent reactive armor systems that are far lighter than conventional reactive armor systems due to the materials used therein. The reactive armor of embodiments of the present invention is composed of at least three layers.
