Abstract
An optical system of a Transmission Electron Microscope (TEM) is configured to use a square-shaped electron beam. Preferably, the square-shaped electron beam is produced by using an aperture with a square hole positioned in an aperture plane of TEM's beam shaping aperture (typically, the C2 lens). The square beam enables exhaustive tiling and data collection, enabling the complete imaging of large biological objects. In single particle analysis, a square beam also speeds up data collection rates. These improvements come with no significant loss in imaging quality compared to the standard round beam method of imaging.
