Figure 3. Images of the nanosphere aggregates:
(a) scanning microscopy and (b) srSESF microscopy. Images (a,b) were formed using the wavelength range 1230 nm–1370 nm, NA = 0.5. Size of magnified portions in the images (a,b) is 1000 nm × 1000 nm. (c) Conventional bright field image using visible light, NA = 0.9. Scale bar is 2 microns.
