Journal: | Applied Physics Letters | 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. | URI: | https://hdl.handle.net/10356/144296 | ISSN: | 0003-6951 | DOI: | 10.1063/5.0013823 | Rights: | © 2020 The Author(s).
