| Title: | Superoscillatory quartz lens with effective numerical aperture greater than one | Authors: | Yuan, GH Lin, YH Tsai, DP Zheludev, NI |
Issue Date: | 13-Jul-2020 | Source: | Applied physics letters, 13 July 2020, v. 117, no. 2, 021106, p. 021106-1 - 021106-3 | Abstract: | We report super-resolution high-numerical-aperture and long-working-distance superoscillatory quartz lenses for focusing and imaging applications. At the wavelength of λ = 633 nm, the lenses have an effective numerical aperture of 1.25, a working distance of 200 μm, and a focus into a hotspot of 0.4λ. Confocal imaging with resolution determined by the superoscillatory hotspot size is experimentally demonstrated. | Publisher: | AIP Publishing LLC | Journal: | Applied physics letters | ISSN: | 0003-6951 | EISSN: | 1077-3118 | DOI: | 10.1063/5.0013823 | Rights: | © 2020 Author(s).
