“I’m tremendously excited about the Celeritas camera. The high speed lets us acquire 4D STEM data like strain maps over large areas and outrun some of the instrumental instabilities of our microscope. It also enables a variety of time-resolved in situ 4D STEM experiments that are impossible without it, like measuring crystal nucleation and growth rates and characterizing the fluctuating atomic structure of supercooled liquids.”

“I am thrilled to hear about this new camera. Performing electron counting in hardware represents a significant advance in CMOS camera technology. The resulting linearity and low noise of the Apollo camera, along with its larger pixel size, is a very smart, well-optimized design. I expect this technology to have a major impact on future applications of cryo-EM.”

“The Direct Electron DE-64 offers a very large CMOS-based direct-detection device that has a level of versatility not available from rival products.”​ “The DE64 delivers an excellent detective quantum efficiency.”
