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. Se producen dispositivos de transmision de luz, tales como lentes y ventanas para dispositivos electronicos portatiles, utilizando una tecnica de moldeo por inyeccion/compresion en la cual un molde del dispositivo de transmision de luz incluye un canal integral sustancialmente en el mismo plano y sustancialmente con el mismo grosor de pared que el dispositivo de transmision de luz que sera producido; los dispositivo de transmision de luz terminados son mecanicamente separados del producto moldeado; se puede aprovechar equipo y procedimiento de moldeo tradicionalmente utilizados para producir discos de informacion para producir dispositivo de transmision de luz; se pueden llevar a cabo diversos procedimientos para anadir metalizacion, revestimientos, e impresion a los dispositivos de transmision de luz.
