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 ...

It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...

3D microscopes do already exist, but they work slowly and give poorer results. The most common type works by recording pixel after pixel in series, which are then assembled into a 3D image. This takes ...
