摘要:
A method and system for enhanced demolding of injection molded optical devices are disclosed. In one embodiment the system includes a metal moldplate without a coat of release layer and a curing device that generates high intensity pulses of UV light. The method includes: providing a moldplate made of a predetermined moldplate material; directly injecting optical material into cavities of a moldplate without a release layer; rapidly curing the injected optical material with high intensity pulses of UV light such that a predetermined optical device is formed; and separating the thus formed optical device from the cavities of the moldplate due to a differential thermal expansion between the optical device material and the moldplate material.
