Claims
- 1. Method of making a double-sided microlens, comprising the steps of:providing a first mold base having alignment members and a mold cavity; providing a second mold base having alignment members and a mold cavity; mounting a first microlens mold, formed in a substrate, in said mold cavity of said first mold base; mounting a second microlens mold, formed in a substrate, in said mold cavity of said second mold base and adjusting said second microlens mold in said mold cavity of said second mold base; supportedly arranging said first mold base and said second mold base on a first platen and an opposed second platen, respectively, of a molding apparatus; press closing said first platen upon said opposed second platen of said molding apparatus and aligning said fist and second microlens molds in said first mold base and said second mold base forming a single mold cavity; introducing a molten plastic into said single mold cavity; and solidifying said molten plastic in said single mold cavity and forming a double-sided microlens.
- 2. The method recited in claim 1 wherein including the step of forming each of said microlens molds in a polygonal substrate with a diamond cutting member.
- 3. The method recited in claim 2 wherein said generally polygonal substrate comprises materials selected from the group consisting of: hardened nickel; nickel alloy; brass; copper; aluminum, and silicon.
- 4. The method recited in claim 2 wherein said generally polygonal substrate is hardened nickel.
- 5. The method recited in claim 2 wherein said diamond cutting member has a generally spherical shape.
- 6. The method recited in claim 2 wherein said diamond cutting member has a generally aspherical shape.
- 7. The method recited in claim 2 wherein said diamond cutting member has an anamorphic shape.
