Abstract

The possibility of the fabrication of film axicons with large focal lengths is shown experimentally. The fabrication technology includes vacuum deposition of layers of chalcogenide glass of variable thickness, which varies linearly depending on the substrate radius. Axicons with focal lengths up to 15 m are obtained.
