... lenses. Results showed that a common plano-convex lens displayed chromatic and spherical aberrations, whereas more expensive aspheric and doublet lenses exhibited mostly chromatic aberrations. ...

... most treasured. Using a pair of scanning transmission electron microscopy (STEM) instruments for which spherical aberration (a system fault yielding blurry images) is corrected, researchers at the ...

... to reduce drift and, perhaps most importantly, the ability to provide optical corrections for spherical aberration (blurring). By making points of light look like disks, spherical aberrations have ...

... to see individual tungsten atoms on the zirconia substrate," says Zhou. "If you can correct the spherical aberration in the microscopy, this allows you in HAADF mode to pick up the heavy tungsten ...
