Fig. 4From: Abnormal shadow contrast imaging for optimal objective lens condition in transmission electron microscopeAdjusting of mechanical alignment of OL P/Ps and thus shadow contrast imaging of AuNPs. a Schematic diagram of the mechanical alignment of OL P/Ps. b Shadow contrast imaging of AuNPs according to the magnitude of mechanical misalignment of OL P/Ps. The length and direction of shadow contrast (red arrows) are proportional and considered to the magnitude and direction of OL P/Ps misalignment, respectivelyBack to article page
