Abstract
Abstract Conoid surfaces can be generated by rotation of a material at different angles and under differing constraints. An axis of 45° can produce hyperboloids; with perpendicular axes, concentric spheres can be produced; magnetic fields can be used to shape the lenses; and multielement lenses can be produced with special chambers.
