Hybrid refractive-diffractive lenses combine the light efficiency of refractive lenses with the information encoding power of diffractive optical elements (DOE), showing great potential as the next generation of imaging systems. However, accurately ...

Prototyping and small volume production of custom imaging-grade lenses is difficult and expensive, especially for more complex aspherical shapes. Fluidic shaping has recently been proposed as a potential solution: It makes use of the atomic level ...
