Plan-apochromat microscope objectives set the benchmark for precise, high-resolution imaging with exceptional color accuracy. By correcting chromatic and spherical aberrations while maintaining a flat ...

Researchers have proposed a new method to form an electron lens that will help reduce installation costs for electron microscopes with atomic resolution, proliferating their use. Instead of the ...

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 ...

IT is known that the spherical aberration of electron lenses sets a limit to the resolving power of electron microscopes at about 5 A. Suggestions for the correction of objectives have been made ; but ...

Researchers at the University of Illinois at Urbana-Champaign have shown for the first time that expensive aberration-corrected microscopes are no longer required to achieve record-breaking ...

Left: Images of fluorescent particles that are above, at and below (top to bottom) the vertical position of best focus of a microscope. Calibrating the effects of lens aberrations on the apparent ...

When using a measurement microscope, users can measure the size and dimensions of sample features in both two and three dimensions, which is important for inspection, quality control (QC), failure ...
