ABSTRACT:
A method of replicating an optically flat surface includes providing a plastic optical element having a machined flat surface. The machined flat surface includes a plurality of ridges thereon. A coating material is applied to an optically perfect flat and the optical element is rolled and positioned on the coating material applied to the optically perfect flat such that grooves between the ridges with the coating material. The coating material sandwiched between the optical element and the optically perfect flat is cured and the optically perfect flat is removed from the cured coating material.
