Process for providing an essentially homogeneous optical element, for example an optical lens, comprising the steps of:
filling a mould with a mixture comprising one or more monomers, one or more initers, and one or more radical polymerization initiators, the degree of polymerization of the monomers during filling being less than 5 % by weight,
polymerizing said mixture such that more than 90 % by weight of all monomer is polymerized, and
removing the essentially homogeneous optical element from the mould.
提供基本均匀的光学元件(例如光学透镜)的工艺,包括以下步骤
用一种或多种单体、一种或多种
引发剂和一种或多种自由基聚合
引发剂组成的混合物填充模具,填充过程中单体的聚合度小于 5%(按重量计)、
聚合所述混合物,使所有单体的聚合度超过 90%(按重量计),以及
从模具中取出基本均匀的光学元件。
