CURVED LENSES CONFIGURED TO DECODE THREE-DIMENSIONAL CONTENT
First Claim
1. A lens configured to decode three dimensional content comprising:
- a polarizing layer laminated with a polymeric material layer on one or both sides;
a retarder layer laminated to a front of the polarizer layer directly or to the polymeric material to form a sheet, said retarder layer aligned to decode a desired circular polarization; and
wherein a blank cut from the sheet is curved using a press polishing process into a lens configured to decode three dimensional content.

Abstract
Curved lenses configured to decode three dimensional content and method of fabricating the same. The lenses comprise a polyvinylalcohol polarizer film or similar type of material laminated with triacetate or similar type material on one or both sides, wherein the polarizer film has a polarizing efficiency equal to or exceeding 99% and a transmittance percentage equal to or exceeding 35% and a retarder film (e.g., norbomene copolymer resin) laminated on a front surface of the polyvinylalcohol polarizer film laminated with triacetate and aligned to produce a desired circular polarization responsive to specified retardation wavelengths. Thermoforming and press polishing techniques may be used to fabricate/curve the blanks into lenses. The lenses (optical elements) may be used in an injection molding process to add thickness.
