(2) Figure 1b: Optical image of the quartz SOL (Figure 1b.tif). (3) Figure 1c: SEM image of the quartz SOL (Figure 1c.tif). (4) Figure 1d: The depth profile of the lens fabricated by optical lithography and with confocal measurement. The *.tif files give the original experimental data. __________________________________________________________________________________ Figure 2: (1) Figure 2a: Simulated y-z cross-section of intensity distribution of the superoscillatory hotspot near the designed focus (Figure 2a.tif). (2) Figure 2b: Simulated x-y cross-section of intensity distribution of the superoscillatory hotspot near the designed focus (Figure 2b.tif). (3) Figure 2c: Experimental y-z cross-section of intensity distribution of the superoscillatory hotspot near the designed focus (Figure 2c.tif). (4) Figure 2d: Experimental x-y cross-section of intensity distribution of the superoscillatory hotspot near the designed focus (Figure 2d.tif). (5) Figure 2e: Comparison of axial intensity of the hotspot between simulation and experiment (Figure 2e.tif). The *.txt files are used to produce the figure 2e in the main text. (6) Figure 2f: Comparison of spot size of the hotspot between simulation and experiment (Figure 2f.tif). __________________________________________________________________________________ Figure 3: (1) Figure 3a: Schematics of the experimental setup for the imaging with superoscillatory hotspot and confocal detection. The figures in *.tif format are used to produce the inset figures. (2) Figure 3b: SEM image, superoscillatory (with SOL) and diffraction-limited (with a normal objective of NA=0.95) imaging of hole pair arrays. The figures in *.tif format are used to produce the figure 3b in the main text. (3) Figure 3c: SEM image, superoscillatory and diffraction-limited imaging of a complex image (Ursa Major and Ursa Minor). The figures in *.tif format are used to produce the figure 3c in the main text. __________________________________________________________________________________ Date of data collection: not given Information about geographic location of data collection: not given Licence: CC BY https://creativecommons.org/licenses/by/4.0/ Related projects: This work was supported by the Singapore Ministry of Education (Grant No. MOE2016-T3-1-006), the Agency for Science, Technology and Research (A*STAR) Singapore (Grant No. SERC A1685b0005), the Engineering and Physical Sciences Research Council UK (Grants No. EP/N00762X/1 and No. EP/M0091221).
