Abstract
A micro-lens array and a method for making are described. The micro-lens array includes a base element and a plurality of lenses formed of an epoxy and including nanoparticles. The micro-lens array is formed from a master micro-lens array, which is placed within a replica micro-lens making assembly. The master micro-lens array is coated with an anti-stiction material prior to having an elastomeric material positioned over it and cured. Removal of the elastomeric material provides a plurality of cavities, which are filled with an epoxy including nanoparticles. Curing of the epoxy finishes the fabrication of the micro-lens array. The lenses of the micro-lens array are formed from a colloidal suspension of nanoparticles and resin.
