A simple plane wave lens, using an inert central plastic wave shaper, has been designed. An experiment was done with a 4 in diam, zeroth order design. An iterative technique that uses measured time deviations to connect the next wave shape was developed. Two identical versions of the first iterated shape were fired. Arrival time deviations in these first iterates fell within 50 ns bonds. With greater care and further iterations, lenses bound by 10 ns deviations seem possible.
