Fig. 1: The 4D-SCED setup.

From: Seeing structural evolution of organic molecular nano-crystallites using 4D scanning confocal electron diffraction (4D-SCED)

Fig. 1

a Typical STEM setup where detector(s) is(are) located at far field. b Defocusing the probe mitigates limited dose budget for radiative sensitive samples. c Scheme of a simplified optic path to realize scanning confocal electron diffraction. OL objective lens, DL diffraction lens. d A simple geometric consideration of spatial and angular resolution.
