Abstract
A method of making a long, thin, flexible lens. The method comprises the steps of providing a mold having a top surface shape corresponding to a desired lens shape. A curable optical material is dispenses onto the top surface. A thin, flexible structural layer is placed onto the top surface, over the curable optical material to form a mold assembly. The mold assembly is cured. The flexible lens is removed from the mold top surface. The flexible lens is capable of flexing in at least a 180.degree. arc while maintaining its diffraction limited optical characteristics.
