This Small Business Research Program project will develop novel spherical microlenses with controlled, radially graded refractive index for advanced optical applications, including laser tracking, remote sensing, and communications, among others. Much theoretical and practical interest has focused on spherical graded index (GRIN) lenses because their spherical symmetry allows them to accept and manipulate light beams from any angle, so that orientation of the lens is unnecessary. However, production of these lenses (sometimes called fisheye or cat's eye lenses) has been impractical due to a lack of methods to produce a spherically graded index of the required profile and magnitude. The research team will develop production of spherical GRIN microlenses of high optical quality, in an economical high volume process using fluidized bed chemical vapor deposition (FBCVD). The team will demonstrate the feasibility of the new process at the bench scale in a binary oxide glass system and characterize the product by physical and optical techniques. If successful the benefits of success could be much better devices for atmospheric monitoring and improved automated metrology.

该小型企业研究计划项目将开发新型球形微透镜，其具有受控的径向渐变折射率，用于先进的光学应用，包括激光跟踪，遥感和通信等。许多理论和实践兴趣都集中在球面梯度折射率（GRIN）透镜上，因为它们的球面对称性允许它们接受和操纵来自任何角度的光束，使得透镜的取向是不必要的。然而，由于缺乏产生所需轮廓和大小的球形渐变折射率的方法，这些透镜（有时称为鱼眼或猫眼透镜）的生产是不切实际的。该研究团队将开发高光学质量的球形GRIN微透镜的生产，采用流化床化学气相沉积（FBCVD）的经济大批量工艺。该团队将在二元氧化物玻璃系统中以实验室规模证明新工艺的可行性，并通过物理和光学技术表征产品。如果成功，成功的好处可能是更好的大气监测设备和改进的自动计量。
