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.
ED pattern acquisition for optimized ASTAR , ADT 3D and strain applications can be obtained through special TOPSPIN module for various CCD /DD cameras : Merlin QD, Dectris Quadro, Gatan Orius , Gatan OneView
