Lenses used in electron microscopy have aberrations that limit their resolution. Successful correction of spherical aberration is now possible, opening the door to three-dimensional, sub-ångström ...

FLORENCE – A new laser ablation profile based on the modification of spherical aberration seems to effectively address presbyopia in a significant number of cases with no loss in quantity and quality ...

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 ...

BERKELEY, CA -- TEAM 0.5, the world's most powerful transmission electron microscope -- capable of producing images with half-angstrom resolution (half a ten-billionth of a meter), less than the ...
