The units in Figure 3c,d and Figure 5a–d of the originally published article are hereby corrected. In Figure 3c,d, the units on the x-axis and y-axis of (c) should be x(λ) and z(λ). The units of x-axis, y-axis, and z-axis of (d) should be x(λ), y(λ), and z(λ). These replace x(µm) and y(µm) for (c) and x(µm), y(µm), and z(µm) for (d). The corrected Figure 3c,d is shown below. 3 Figure (Figure presented.) c) Intensity distribution of the focusing spot in the x–z plane. d) 3D representation of the focal spot. Three shells correspond to 0.4, 0.6, and 0.9 of the peak intensity, respectively. 5 Figure (Figure presented.) a,b) The experimental lateral (a) and axial (b) intensity distributions in the x–y and x–z planes. c,d) The cross-section intensity profiles along the y direction (c) and the z direction (d). e) 2D lateral (black) and axial (blue) focal spot size as a function of thickness of 2D perovskite. f) Cross-section lateral focal intensity of 2D perovskites with different compositions. The main text on Page 5 (line 13–15, right column), “Figures 3c and d illustrate the simulated intensity distribution of the focusing point in the x–y plane and its 3D representation, respectively” is also corrected to: “Figures 3c and d illustrate the simulated intensity distribution of the focusing point in the x–z plane and its 3D representation, respectively.” Similarly, in Figure 5a,b, the labels on the x-axis are corrected to x(µm) instead of x(λ) and the labels in Figure 5c,d are corrected for consistency. In Figure 5f, the intensity is normalized here in order to make a clear lens performance comparison between the perovskite-based lenses with different compositions. The corrected Figure 5 is shown below:.
