Fig. 5: Quantitative phase imaging of unstained bio-samples with the meta-microscope.
From: Quantitative phase imaging with a compact meta-microscope
a Photograph of the meta-microscope (length: 36 mm, width: 36 mm, and height: 14 mm). b Schematic illustration of the meta-microscope with the distance between the metalens surface and the CMOS as H = 7 mm, resulting an imaging magnification of 4. CPF represents circularly polarized film. c, e In-focus images of HeLa and 4T1 cells captured by the meta-microscope at λ0 = 450 nm. d, f Reconstructed in-focus phase profiles of the corresponding cells from the image stack obtained by the meta-microscope. Scale bars in c–f are 20 μm.
