In the original paper, the line width of the resolution target (which corresponds to half-pitch resolution) was used to characterize the resolution of our microscope system. However, we think that full-pitch resolution offers a better definition of the imaging system’s resolution limit. In this erratum, we list specific sections from the manuscript that used half-pitch resolution and correct them accordingly.

In section 1, paragraph 2 of our original paper [1], we cited our first work on Fourier ptychographic microscopy [2] stating that it is ‘a high-resolution (0.78 µm, 0.5 NA), wide-FOV (~120 mm2) microscope with a final SBP of ~1 gigapixel’. As mentioned in the corrigendum of Ref. [2,3], the reported resolution for the microscope was its half-pitch resolution. However, full-pitch resolution offers a better definition of the imaging system’s resolution limit. Here we correct that the reported FPM system has 1.56 µm full-pitch resolution and ~0.23 gigapixel spatial bandwidth product.
In section 5, paragraph 3 of our original paper [1], we stated that ‘As shown in Fig. 6(c3), 6(c4), group 9 element 3 can be resolved, resulting in a resolution of ~780 µm throughout the entire FOV.’ We hereby correct this statement: ‘As shown in Fig. 6(c3), 6(c4), group 9 element 3 can be resolved, resulting in a resolution of ~1.56um throughout the entire FOV.
