Abstract

In this paper, we demonstrate the manufacturing of diffractive optics for frequencies as high as 1 THz using a relatively simple and cost-effective fused deposition modelling (FDM) 3D printing technique. Four diffractive lenses were designed and manufactured from the cyclic olefin copolymer (COC). Fabrication of diffractive lenses for such high frequencies was possible due to an unusually small nozzle, refined printing procedures and a very transparent material. For the two of the manufactured lenses, more than twofold improvement in focusing efficiency has been shown in a direct comparison with their refractive counterparts. Moreover, the other two elements demonstrated the feasibility of lenses with very small f-numbers (0.95 and 0.63) with this technique.
工作频率为 1 太赫兹的 3D 打印衍射透镜
在本文中,我们展示了如何利用相对简单且经济高效的熔融沉积建模(FDM)3D 打印技术制造频率高达 1 太赫兹的衍射光学器件。我们用环烯烃共聚物(COC)设计并制造了四个衍射透镜。之所以能制造出如此高频率的衍射透镜,是因为采用了异常小的喷嘴、精细的打印程序和非常透明的材料。所制造的两个透镜与折射透镜相比,聚焦效率提高了两倍多。此外,其他两个元件也证明了用这种技术制造极小光圈数(0.95 和 0.63)透镜的可行性。
