On the left is the section in relation to the mushroom and its cap; on the right is a schematized diagram of part of the section, under your microscope. Use good razor blades! Prepare to budget some money for razor blades, because successful sectioning requires super sharp edges. We're ...
Since the microscope's resolution depends on a small electron wavelength, and since that is inversely proportional to its momentum, the microscope needs very fast electrons, accelerated by a large electric potential. Thus the electron source is maintained at a negative potential around 100 kV, so ...

Finally, the scanning tunnelling microscope, invented in 1982, uses not a beam but an electron wave field, which by interacting with a nearby specimen is capable of imaging individual atoms; its resolution is an astounding one Angstrom. Bibliography See C. Marmasse, Microscopes and Their Uses (...

Envelope functions characterizing (a) spatial and (b) temporal partial coherence. An important feature of the function sin γ is that it gives us a convenient measure of the resolution of the microscope. Beyond the first zero of the function, information is no longer transferred faithfully, but...
We characterized the optical resolution of the objective by imaging 200-nm fluorescent beads at 800-nm excitation wavelength (Fig.2d,e). In air (NA = 0.69), we measured an on-axis point spread function (PSF) with a full width at half maximum (FWHM) of 0.56 ± 0.01 µ...
