THERMOCOMPRESSION MOLDING OF PLASTIC OPTICAL ELEMENTS

摘要

Methods of forming a plastic element include dispensing a quantity of a liquid precursor material into a first die mold, positioning a carrier tape on the first die mold above the dispensed liquid precursor material, bringing a second die mold into contact with the carrier tape and the first die mold, and applying pressure to the first die mold and the second die mold. The liquid precursor material may include a liquid silicone. Multiple lenses may be produced in the form of a sheet, and individual lenses separated from the sheet after moulding. The plastic may be at least partially cured whilst in the mould.
