Abstract

Element descriptador optico reversible, that being the type of which are performed in a optically transparent material in one of whose sides is carving surfaces parallel of circular optically convergence, or surfaces spherical optically conergentes, essentially is defined because in correspondence with face provided with said surfaces carved adds a frame perimeter, same or different material, with the special feature that the thickness of said frame equals the focal distance in air spherical or cylindrical component of the plot lens, the other side and plain a gap between the front and back equal to the focal length of the lens spherical or cylindrical within the substance that constitutes optically transparent.
