Abstract

An anamorphic lens (10) having a first surface (14) which has either a cylindrical or an acylindrical radius of curvature, and a second surface (16) having either a cylindrical or an acylindrical radius of curvature. Each surface has a primary longitudinal axis (22, 24), which is preferably but not necessarily orthogonal to the optical axis (18) of the lens (10); and the longitudinal axes are crossed. Preferred applications for the anamorphic lens include non-image forming illumination systems wherein independent illumination control in two coplanar directions at the object is desired. A process for recycling a single use camera having such an anamorphic lens is also disclosed.
