The Center for Freeform Optics (CeFO) is a partnership between the University of Rochester (UR) and the University of North Carolina at Charlotte (UNC Charlotte). CeFO is advancing research and education in the science, engineering, and applications of freeform optics through dedicated, long-term partnerships with industry and government laboratories. CeFO is motivated by the need for compact, affordable, high-performance optical systems to support the precision technologies of the 21st century. Freeform optics specifically enables compact optical solutions for complex light mapping as well as folding optical systems in three-dimensions. Applications with immediate benefit include 3-D imaging and visualization, augmented and virtual reality, infrared and military optical systems, efficient automotive and LED lighting, energy research, remote sensing, semiconductor manufacturing and inspection, and medical and assistive technologies. CeFO enables freeform optics to permeate the marketplace through integration of fundamental and applied research and significant advances in design, fabrication, and testing.CeFO creates a fertile, dynamic, inclusive multidisciplinary environment to move this technology to the forefront. The partner universities are dedicated to the recruitment and retention of women and students from underrepresented groups (i.e. 34% underrepresented students in CeFO in Spring 2017) to create a diverse and skilled workforce for the 21st century.The Center for Freeform Optics (CeFO) vertically integrates mathematics, materials science, optical science, optical instrument design, optomechanics, and precision optical manufacturing, measurement, and testing to transform the optics industry in the 21st century. CeFO constitutes a unique research environment combining the strengths of two world class research universities with specialized experiences, insights, and interdisciplinary talents for designing, building and measuring advanced optical systems. The University of Rochester's expertise in?optical theory, design, and metrology?complements UNC Charlotte's excellence in?fabrication, metrology and precision opto-mechanical design. Research topics of immediate interest to industry include the mathematical description of freeform surfaces, the quantification of mid-spatial frequency errors on optical performance, and wave-based modeling of freeform systems and new bases for 3D optical design. Additional challenges include use of difficult optical materials, characterization and elimination of mid-spatial frequency errors, volume manufacturing (e.g. replication, molding, 3D printing), and advanced metrology for freeform surfaces. Freeform optical systems will enable innovation in sensing, imaging, visualization and diagnostic instrumentation by directing light in 3D. The partner Universities demonstrate excellent records in recruiting women and minority students (30% of graduate students in the program). Students work with CeFO industrial members to communicate and transfer key enabling technologies.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

自由形式光学中心（CEFO）是罗切斯特大学（UR）与北卡罗来纳大学夏洛特大学（UNC夏洛特）之间的合作伙伴关系。 CEFO通过与行业和政府实验室的专门长期合作伙伴关系来推进科学，工程和自由形式光学的应用。 CEFO的激励是需要紧凑，负担得起，高性能的光学系统来支持21世纪的精确技术。 FreeForm光学器件专门为复杂的灯光映射以及三维折叠光系统提供紧凑的光学解决方案。具有直接利益的应用包括3D成像和可视化，增强和虚拟现实，红外和军事光学系统，有效的汽车和LED照明，能源研究，遥感，半导体制造和检查以及医疗和辅助技术。 CEFO使FreeForm Optics能够通过整合基础和应用研究，并在设计，制造和测试方面取得重大进展来渗透到市场。CEFO创造了一个肥沃的，充满活力的，包容的多学科环境，以将这项技术推向前沿。伙伴大学致力于招募和保留代表性不足的群体（即2017年春季CEFO的34％代表性不足的学生）为21世纪创建多样化和熟练的劳动力。测量和测试以改变21世纪的光学行业。 CEFO构成了一个独特的研究环境，该环境结合了两种世界一流的研究大学的优势以及用于设计，建设和测量高级光学系统的专业体验，见解和跨学科才能。罗切斯特大学在光学理论，设计和计量学方面的专业知识？对夏洛特的卓越表现为“制造，计量和精确光学机械设计”。 行业直接兴趣的研究主题包括自由形式表面的数学描述，光学性能中空间频率错误的量化以及基于波浪的自由形式系统和3D光学设计的新基础的模型。其他挑战包括使用困难的光学材料，表征和消除中间空间频率错误，体积制造（例如复制，成型，3D打印）以及自由形式表面的高级计量学。 Freeform Optical系统将通过指导3D中的光线来实现传感，成像，可视化和诊断仪器的创新。合伙大学在招募妇女和少数民族学生（该计划中的研究生中有30％）展示了出色的记录。学生与CEFO工业成员合作进行交流和转移关键启用技术。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响标准，被认为值得通过评估来获得支持。
