Abstract

Wide field-of-view optics are crucial optical elements with extensive applications in imaging, display, and sensing. Conventional wide FOV optics rely on cascading multiple refractive optical elements to assemble ‘fisheye lenses’ that correct third-order Seidel aberrations. Here we experimentally demonstrate a flat lens design that achieves 140◦ FOV in the long-wave infrared band. The metalens was fabricated on a monolithic float zone Si wafer leveraging photolithography and deep reactive ion etching. Large metalenses with diameter exceeding 4 cm have been realized using this approach. Thermal imaging at ambient temperature was validated by coupling the metalens with a LWIR focal plane array.
