*9661615郑这个小企业创新研究第二阶段是针对包含分布折射率的光学材料，用于透镜设计，称为梯度折射率(GRIN)材料，在光学系统中有广泛的应用。在这项拟议的研究中，我们计划通过溶胶-凝胶溶液的分层将超临界干燥技术整合到轴向GRIN玻璃的制备中，因为这种技术已经被证明是低成本和快速的。此外，将对新的玻璃成分进行测试，以实现良好的化学耐久性。这种AGRIN透镜的主要应用是各种光学系统。使用轴向GRIN透镜可以减少三分之一的透镜。提出的溶胶-凝胶分层技术有望成为低成本、可设计轴向梯度折射率透镜在光学系统中的普遍应用和发展前景。***

*** 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. ***
