I am trying to find the easiest way to create a working lens and i developed a idea .
As you know diffractive optics reduced the used glass elements in canon teleobjective.
And diffractive optics used at eyeglasses for to open a window at eye view with new focal lenght.
Canon printed emboss of a polymer on glass lens element and cured it with uv.
And mit jacobsen at media lab printed very large integrated circuits - for example pentium - on to the flexible plastic film with a hand operated stamp.
Why not do we produce laser engraved stamps for to print our diffractive optics lenses with uv hardenable inks ? These prints could be applied on high diffractive index glass or polymer composite sheets or blocks ,films , single or multiple layers.
