Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which ...

A computer-assisted design schematic showing how an electron beam is routed within a microscope. After going through the sample, it crosses a bright cyan beam representing the laser beam. A schematic ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

(A) When a traditional Gaussian beam is used, diffraction causes the illumination beam to widen at the edges. (B) Joint optimization scheme. A network predicts the positions of beads in the focal ...
