Abstract
A system for projecting one or more synthetic optical images, which demonstrates improved resistance to optically degrading external effects, is provided. The inventive system serves to lock the focal length of the focusing elements in place. In other words, no other transparent materials or layers brought into contact with the inventive system will serve to materially alter the focal length or the optical acuity of synthetic images formed by the system.
