Jointly acquired HAADF and MAADF signals
The HAADF signal (left) contrast is easily interpreted in terms of mass thickness of the material while the diffraction contrast MAADF signal (right) reveals highly detailed structural changes in the material. The optimized geometry makes this possible.

Image of interplanetary dust particle; STEM tilt series acquired with a 806 HAADF detector from -61˚ to 68˚; aligned, reconstructed and visualized using 3D reconstruction and 3D visualization software; the iso-surfaces highlight two different intensity levels in the reconstruction.
First 3.2 Å β-galactosidase structure solved by cryo-EM
Bartesaghi, A.; Matthies, D.; Banerjee, S.; Merk, A.; Subramaniam, S.
Structure of Escherichia coli β-galactosidase (∼465 kDa) at 3.2 Å resolution solved using the GIF Quantum LS energy filter that includes a K2 Summit camera. The first atomic model derived using single-particle cryo-EM analysis closely matches the 1.7 Å crystal structure with a global rmsd of ∼0.66 Å.

High resolution image of Au nanoparticles, drift correction off (image 1)
Image of gold (Au) nanoparticles shows the impact sample motion may have on an image when drift correction is turned off. See High-resolution image of Au nanoparticles, drift correction on (image 2 and 3) in the OneView media library to see how OneView minimizes the impact of sample motion when drift correction is turned on.
