Abstract
According to one aspect of the invention, there is provided a method of forming a film with a lenticular lens array, the method comprising providing a substrate; providing a mold having a plurality of nano-scale to micro-scale cavities that form the lenticular lens array on the substrate; having the mold contact the substrate; and forming the lenticular lens array by allowing portions of the substrate to partially fill the plurality of cavities.

A method of forming a film with a lenticular lens array wherein each lens of the lenticular lens array has an optimum focal length, the method comprising:
- providing a substrate;
- providing a mold having a plurality of nano-scale to micro-scale cavities that form the lenticular lens array on the substrate;
- having the mold contact the substrate;
- and
- forming the lenticular lens array by bringing the substrate to within 10° below and 10° above its glass transition temperature to cause the substrate to be in high viscosity allowing portions of the substrate to partially fill the plurality of cavities so that each lens of the lenticular lens array has an optimum focal length.
