Superoscillatory quartz lens with numerical aperture greater than one
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, working distance of 20 μm and focus into a hotspot of 0.4λ. Confocal imaging with resolution determined by the superoscillatory hotspot size is experimentally demonstrated.

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, working distance of 20 μm and focus into a hotspot of 0.4λ. Confocal imaging with resolution determined by the superoscillatory hotspot size is experimentally demonstrated.
