In 1931, electromagnetic lenses helped scientists see a world ordinary microscopes could not reach
In 1931, physicists Knoll and Ruska unveiled the first electron microscope, revolutionizing science by using magnetic lenses ...
A comparison of experimental annular dark field (ADF)-scanning transmission electron microscopy (STEM) and electron ptychography in uncorrected and aberration-corrected electron microscopes. In the ...
Field-resolving metrology of electromagnetic waves has heralded a revolution in the science of light–matter interaction. By exploiting calibrated nonlinearities to directly map the time evolution of ...
Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which ...
Spherical aberration in an optical system causes rays that pass farther from the optical axis to be focused closer to the lens than those passing near the axis, resulting in a blurred focal spot and ...
