To demonstrate the results of the ray tracing-type aberrometer in measuring spherical aberration (SA) in pseudophakic eyes with monofocal intraocular lens (IOL), aspheric monofocal IOL, or aspheric ...

Light travels at different speeds based on the medium it passes through. For example, in a vacuum, it travels at 3.0 × 10^8 m/s in a straight line. But when directed towards glass, air, diamond, water ...

Not an aberration: schematic drawing of the metalens (left), which is made of tiny titanium waveguides. The drawing on the right is of a single waveguide. (Courtesy Boubacar Kanté) A new type of ...

SEAS researchers have developed a so-called metacorrector, a single-layer surface of nanostructures that can correct chromatic aberrations across the visible spectrum and can be incorporated into ...

THE steeply curved surface of the field lens of a Kellner-type eyepiece usually introduces considerable spherical aberration of the principal rays. Frequently, this aberration cannot be corrected ...
