Advance to Brillouin microscopy by a European Molecular Biology Laboratory-engineered team widens the aperture and provides ...

When light passes through an aperture, such as the objective lens of a microscope, it undergoes diffraction and spreads out. This diffraction causes the light to form a diffraction pattern, known as ...

IN a recent paper 1 I derived formulæ expressing the distribution of light in the geometrical focal plane of optical systems of high relative aperture; and, using these formulæ, curves were ...

Placing a hair before this simply-constructed instrument, he found to his great joy that he was the maker and possessor of a capital microscope for those times, and he secured to the micrographers ...

This meant that a microscope could not resolve two objects located closer than λ/2NA, where λ is the wavelength of light and NA is the numerical aperture of the imaging lens. This diffraction ...

Scanning near-field optical microscope (SNOM) – using the scattered light through a sub-wavelenght aperture to form an image. (Illustration by Kristian Molhave, Opensource Handbook of Nanoscience and ...
