Methods of fabricating optical elements that are encapsulated in monolithic matrices. The present invention is based, at least in one aspect, upon the concept of using multiphoton, multi-step photocuring to fabricate encapsulated optical element(s) within a body of a photopolymerizable composition. Imagewise, multi-photon polymerization techniques are used to form the optical element. The body surrounding the optical element is also photohardened by blanket irradiation and/or thermal curing to help form an encapsulating structure. In addition, the composition also incorporates one or more other, non-diffusing binder components that may be thermosetting or thermoplastic. The end result is an encapsulated structure with good hardness, durability, dimensional stability, resilience, and toughness.
制造封装在单片基质中的光学元件的方法。至少在一个方面,本发明基于使用多光子、多步骤光固化技术在可光聚合组合物主体中制造封装光学元件的概念。使用多光子聚合技术形成光学元件。光学元件周围的主体也通过毯式辐照和/或热固化进行光硬化,以帮助形成封装结构。此外,组合物中还含有一种或多种其他非扩散粘合剂成分,这些成分可以是热固性的,也可以是热塑性的。最终形成的封装结构具有良好的硬度、耐久性、尺寸稳定性、回弹性和韧性。
