Title:
SYSTEM, DEVICE, AND METHOD FOR PRODUCING THIN PLASTIC LENSES
Document Type and Number:
WIPO Patent Application WO2006050230
Kind Code:
A3
Abstract:
Light transmission devices, such as lenses and windows for portable electronic devices, are produced using an injection/compression molding technique in which a light transmission device mold includes an integral runner in substantially the same plane and with substantially the same wall thickness as the light transmission device to be produced. The finished light transmission devices are mechanically separated from the molded product. Molding equipment and processes traditionally used to produce information discs can be leveraged to produce light transmission devices. Various processes can be performed to add metallization, coatings, and printing to the light transmission devices.
