WitrynaTransmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is … Witryna4 kwi 2024 · The ED-1 features multiple magnetic lenses with variable focal lengths and a single beam-limiting aperture with a fixed aperture diameter between the electron source and the sample, designed ab initio and fully optimized for the most accurate diffraction experiments, as well as for imaging in order to visually inspect and …
WitrynaThe metasurface-based superoscillatory lens has been demonstrated to be effective in finely tailoring the wavefront of light to generate focal spots beyond the diffraction limit in the far-field that is capable of improving the resolution of the imaging system. In this paper, an ultra-thin (0.055 λ0) metasurface-based superoscillatory lens (SOL) that … WitrynaOnly a micron thick, their revolutionary "flat" lens is much thinner than a sheet of paper and offers performance comparable to top-of-the-line compound lens systems. The …
