ABSTRACT:
Producing a scaled multiple parallax compound lens is accomplished by providing an insect eye having multiple ommitidia and creating a polymer mold of the insect eye. A casting is then created from the polymer mold with an expandable polymer mold. A second casting is then created from the second polymer mold. Duplication of the process can be accomplished for further scaling up of the compound lens with the final casting created using a durable polymer having appropriate optical properties for the lens.
