Producing Smooth Surfaces on Polycrystalline ZnS Aspheres and Freeforms

Commercially available deterministic polishing methods commonly induce excessive surface roughness, or grain decoration, on polycrystalline aspheres and freeforms. The excessive surface roughness causes optical scatter and limits optimal performance. In current work, a process developed at Opti ....
