摘　　要：大口径菲涅尔透镜已经成为现代新型投影显示终端核心光学器件,受大口径超精密金刚石机床尺寸限制,大口径菲涅尔透镜制造一直是是世界性技术难题,超大口径菲涅尔透镜制造成为新型投影显示领域制造的技术瓶颈。本文发明了一种大口径菲涅尔透镜制造应用创新平台。通过在数控压印光学辊筒超精密金刚石机床上采用金刚石雕刻刀具雕刻菲涅尔微细结构在锥形压印辊筒上的方法,独创一种大口径制造菲涅尔透镜的新方法,同时实现菲涅尔透镜多个领域应用。Large aperture Fresnel lens has become the core optical device of modern new projection display terminal. Due to the size limitation of large aperture ultra precision diamond machine tools, the manufacturing of large aperture Fresnel lens has always been a worldwide technical problem, and the manufacturing of large aperture Fresnel lens has become a technical bottleneck in the manufacturing of new projection display field. This article invents an innovative platform for the manufacturing and application of large aperture Fresnel lenses. By using diamond carving tools to carve Fresnel microstructures onto conical imprinting rollers on a CNC imprinting optical roller ultra precision diamond machine tool, we have created a new method for manufacturing Fresnel lenses with large apertures, while achieving applications in multiple fields of Fresnel lenses.
