Edmund Optics has introduced TechSpec spherical aberrationcompensation plates optimized for use in collimated light with small fields ofview. Leveraging a precision BK7 substrate, these ...

THE method proposed here enables, in principle, the optical system of a conventional electron microscope to be used to determine both amplitude and phase, free from spherical aberration, of the ...

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 ...

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 ...

Over the last 20 years, the proliferation of research utilizing scanning electron microscopy (SEM) has driven the performance of systems towards higher resolution at lower voltages. This enthusiasm is ...

The Electron Optics Facility (EOF) includes three scanning electron microscopes (SEM), an aberration-corrected atomic resolution scanning transmission electron microscope (STEM), and a focused ion ...

One of the oldest problems in optics has been solved. Rafael Gonzalez from Mexico's Tecnologico de Monterrey has come up with an almost comically dense equation that can be used to almost completely ...

Electron microscopy enables researchers to visualize tiny objects such as viruses, the fine structures of semiconductor devices, and even atoms arranged on a material surface. Focusing down the ...
