Buoyancy-based Rapid Prototyping of Lenses
- Current methods for fabricating lenses rely on mechanical processing of the lens or mold, such as grinding, machining and polishing. The complexity of these fabrication processes and the required specialized equipment prohibit rapid prototyping of optical components. This work presents a simple method that leverages the basic physics of surface tension and hydrostatics for rapidly fabricating a variety of lenses with optical surface quality and without the need for any mechanical processing. This approach allows to fabricate all types of spherical lenses(positive, negative, meniscus)over a wide range of sizes and curvatures, as well as lenses of special structure and topography(aspherical, saddle, bi-focal, doublet). The method is inexpensive, does not require specialized equipment, and can be implemented using a variety of curable liquids.
