摘要
A method is disclosed of implementing lens elements or lens arrays having dimensions ranging from a few centimeters down to the micro-scale or nano-scale using the surface tension of the lens material in a molten state to allow the curved shape of the lens to be precisely defined. The method has useful application in the fabrication of lens elements and lens arrays out of a large variety of material types, including elemental materials, as well as compound materials and alloys. The method also allows the implementation of lenses having far superior surface smoothness compared to other approaches, as well as very accurate lens shapes. The method allows the making of high quality lenses and lens arrays, wherein the diameter of the lenses are on the order of a few microns or less. Convex, concave, plano-convex, plano-concave, compound lenses, and many other types of lens shapes can be implemented using the method of the present invention.
