Optical device including at least one replicated surface and associated methods

A method of manufacturing a plurality of optical devices, comprising:

• providing a plurality of non-planar transparent structures on a first surface of a substrate, the base lenses being made of a first material;
• and
• providing a plurality of molded refractive surfaces adjacent corresponding ones of the plurality of non-planar transparent structures on the first surface of substrate, the molded refractive surfaces being of a second material, different from the first material, each optical device including at least one non-planar transparent structure and at least one molded refractive surface.
