Abstract

To produce a transparent optical element, the process starts with the production of an optical component having at least one transparent array of cells that are juxtaposed parallel to one surface of the component, each cell being hermetically sealed and containing a substance having an optical property. This optical component is then cut along a defined contour on its surface, corresponding to a predetermined shape of the optical element. Preferably, the array of cells constitutes a layer having a height of less than 100 μm perpendicular to the surface of the component.
