Fig. 2From: Abnormal shadow contrast imaging for optimal objective lens condition in transmission electron microscopeExperimental images of 10 different SH positions. The SH was adjusted at intervals of 0.33Â mm between 6 and 9Â mm from the top of the lower P/P. Each image from (a) to (j) was focused with an appropriate OL current for 10 SH positions. The red arrows indicate the direction of the shadow contrasts formed from AuNPsBack to article page
