Zusammenfassung:Systems and methods of lens fabrication are disclosed. The method includes initiating transmission of light from a light source through a diffuser into a container containing a resin and a substrate. The light projection is performed according to an irradiation pattern in which each dot in the resin is irradiated by at least 10% of the diffuser. This results in the formation of a lens. To achieve such illumination, at least 15% of the diffuser receives light from the light source. Further, the diameter of the diffuser is greater than or equal to the diameter of the substrate. A system for performing the method includes a polymerization device and may include a resin conditioning and storage device, a metering unit, a resin discharge device, and optionally a post-curing device. 公开了镜片制作的系统和方法。该方法包括启动从光源通过漫射器的光传输到容纳树脂和基材的容器中。根据其中树脂中的每个点被至少10%的漫射器照射的辐照模式进行光投射。这导致形成镜片。为了实现这种照射,至少15%的漫射器接收来自光源的光。进一步地,漫射器的直径大于或等于基材的直径。执行该方法的系统包括聚合装置并且可以包括树脂调节和储存装置、计量单元、树脂排出装置和可选的后固化装置。
