*** 9661615郑这个小企业创新研究的第二阶段是针对光学材料，它包含一个分布式折射率，用于透镜设计被称为梯度折射率（GRIN）材料，在光学系统中有广泛的应用。在本研究中，我们计划整合超临界干燥技术，通过溶胶-凝胶溶液分层来制造轴向GRIN玻璃，因为该技术已被证明是低成本和快速的工艺。此外，新的玻璃成分将进行测试，以达到良好的化学耐久性。这种AGRIN透镜的主要应用是在各种光学系统。使用轴向GRIN镜片可以减少三分之一的镜片。所提出的溶胶-凝胶分层技术有望成为光学系统中制造低成本、可设计的轴向GRIN透镜的通用方法。＊＊＊

*** 9661615 ZHENG This Small Business Innovation Research Phase II is directed towards optical materials which contain a distributed refractive index and are used in lens design are called gradient-index (GRIN) materials which have wide applications in optical systems. In this proposed research, we plan to integrate the supercritical drying technique for the fabrication of axial GRIN glasses via the layering of sol-gel solutions, since this technique has been proven to be low cost and fast process. In addition, new glass compositions will be tested in order to achieve good chemical durability. The principal application of this AGRIN lens is in various optical systems. The use of axial GRIN lenses can reduce one third of lenses. The proposed sol-gel layering technique is expected to be universal and promising way to make low cost and designable axial GRIN lenses in optical systems. ***
