Advanced CCD and Direct Detection cameras
for high end 4D-STEM/SPED applications

 

Advanced  cameras as well as  latest  generation Direct Detection cameras specifically designed for TEM can be used for  ED pattern acquisition for optimized ASTAR ,  ADT 3D,   and  strain applications.Use of such advanced  cameras enable to  increase the speed of ED pattern collection (eg 1000 fps*)and consequently decrease acquisition time for each 4D-STEM/SPED map (speeding up the collection of data with a high-throughput and efficient setup).

Such  cameras  may  also allow to collect ED patterns at much lower  dose rates, making possible to  study beam sensitive materials  and collect ASTAR orientation and strain maps with very low noise while revealing fine structural details.

*The maximum frame rate, number of pixels, their related dynamic range and field-of-view are ultimately specified  by the camera provider.
