A new approach to fabricating microlens arrays (see figure and cover) based on the confinement of surface wrinkles on a soft polymer surface is presented. The dimensions and the arrangement of the microlenses are controlled by the degree of lateral confinement and the material properties of the wrinkled regions. This approach allows for the nonplanar patterning of a polymer surface with a microlens array to form a biomimetic compound lens.
